can power conditioners cause lcd displays to malfunction manufacturer

Whether it’s your dryer tripping a breaker or lighting striking your home, power surges are far too common. Keeping things safe and operating smoothly is the utmost priority, but how much damage can power surges do anyway? Should they be on your list of worries if keeping your TV safe is a priority?

A power surge can damage a TV. The damage can be minimal, such as a single HDMI port no longer working, or it’s possible that it could be completely fried and no longer able to operate. A surge protector is a simple device that will add a layer of protection to any devices connected to it.

The last thing you want is to be in a situation where a little preparation could have saved the day. While protectors are of course important, what causes a power surge anyway? How can you know that a surge is the source of your problems? To find out more about power surges and TVs, read on!

Look, you don’t have to be an electrician to understand that electricity can be dangerous. That’s not just for you either, it can be a real electronics killer if you don’t watch out. So what exactly is happening when you experience a power surge? How does this phenomenon spell disaster for TV?

Also known as transient voltage, power surges are quite simply an increase in voltage. Sometimes this increase is strong enough to damage and destroy the items you have attached to the circuit; which, sadly, includes your TV.

If you’re looking for an exact source, most power surges as caused by items inside the home. Here are some heavy-duty appliances you can usually point your finger at when power surges are a threat:

However, you may also experience an outside power surge. If this is the case, then mother nature is to blame. Things like random lighting strikes are usually the cause of power surges that come from outside. But what actually happens when you experience a power surge?

Well, time to put on your science cap. When an electrical current passes through a device and it happens to exceed the recommended operating range, electrical arcs can destroy the wiring component. Even a small surge can do damage, especially if it happens frequently.

Power surges can be bad news, as you can imagine. While you may not get full device failure, there are some other consequences of power surges that do damage over time rather than all at once. So how can you tell if your TV has experienced a power surge? What should you look out for?

Generally, if a device that was working properly doesn’t anymore, a power surge could be the culprit. If this happens, following a circuit breaker tripping or another electrical event, you can further reduce the possibilities of this happening.

Other than device failure, what else should you look out for? Here are some other signs that you may have experienced a power surge problem in your home:

Device components not working — Check the device’s lights, the clock, or really any other aspect of the TV to see if you can find any abnormalities. This could be a sign of a power surge.

Those are just a quick few things to keep in mind when trying to diagnose a power surge issue yourself. If you are worried or need a second opinion, contact your local electrician. They’ve got the experience you need not only to identify the issue but also to fix it if need be.

Some things are just out of our hands; power surges are one of them. While you can try your best to manage the risks from inside your home, like heavy appliances, you can’t control mother nature. So what should you do to protect your TV from sudden jumps in voltage?

Put quite simply, to protect against power surges, get a surge protector. It’s the only way you can prevent damage from all kinds of power surges, both inside and outside. Without one, you leave yourself open to damage down the road.

A surge protector is a simple device. They help divert voltage spikes safely through the ground, meaning they don’t reach your device but rather go straight toward the earth. The best part? You can get a decent surge protector for very cheap, like this model from Belkin (on Amazon).

However, a cheaper surge protector is not always the best option. Sometimes if your equipment is more expensive or sensitive, then it makes sense to purchase a higher-quality surge protector like the Panamax M8-EX (on Amazon). I’ve been using this model for many years now and never had any issues with it or my devices.

In a perfect world, you’d have surge protectors on every appliance. But that’s just not the case for most people. So what should you do if your TV isn’t working and a power surge seems to be the likely culprit?

The first thing you’ll want to try is performing a power drain. This will make sure that no more residual power is left in your TV and can solve many problems.

This is a great first move and can often be a remedy for even the most troublesome of TV issues. If it still doesn’t work, or your TV is on but acting weird, a factory reset might be the next best option.

Keep in mind that not all TVs will have the same reset process. If you can, use your owner’s manual. You’ll find more specific steps there on how to perform a full factory reset. If neither of these steps fixes your problem, it could be an issue with the power manager for the device. If this is the case, you may need to get external help from a TV repair expert.

When things go south, the first thing you might think of is your insurance. Does homeowner’s insurance typically cover power surges? Since they are so common, many people are asking this question.

In some cases, power surges are protected under homeowner’s insurance if you have protection for personal items. Not all policies will offer this coverage. Get in contact with your local agent for more information on your situation.

Personal Property Coverage is what helps you replace your belongings when they get destroyed by a covered peril. In most cases, a power surge is considered a covered peril. But, there are limits you’ll need to be aware of before calling in a claim.

In almost every situation, the homeowner is responsible for the damage caused by a power surge. Of course, if you have insurance, personal belongings might be covered, but that’s not always the case.

This is why getting proper protection is key to keeping things safe. Look, surge protectors are cheap and can save you thousands on needing to replace your TV outright. Since they usually offer more than one outlet for use, even a single surge protector can help with a whole load of electronics, including your TV. So get some before it’s too late!

Troubleshooting CRTs versus LCDs begins with similar steps, but diverges due to the differing natures of the two display types. The first troubleshooting steps are similar for either display type: power down the system and display and then power them back up; make sure the power cable is connected and that the outlet has power; verify that the signal cable is connected firmly to both video adapter and display and that there are no bent pins; verify that the video adapter is configured properly for the display; try the problem display on a known-good system, or try a known-good display on the problem system; and so on. Once you"ve tried the "obvious" troubleshooting steps, if the problem persists, the next step you take depends on the type of display. The following sections cover basic troubleshooting for CRTs and LCDs.

CRTs seldom fail outright without obvious signs, such as a loud snap or a strong odor of burning electrical components. Most CRT problems are really problems with the power, video adapter, cable, or hardware/software settings. To eliminate the CRT as a possible cause, connect the suspect CRT to a known-good system, or connect a known-good display to the suspect system. It is worth noting, that older CRTs eventually wear out, and starts dimming. Common signs of a weak CRT are a dim picture, dysfunctional brightness and/or color controls, image smearing at high brightness, and in color CRTs, a tint towards a single color (Red Green Blue)

Even if the CRT is in warranty, the shipping costs may exceed the value of the CRT. For example, shipping a CRT both ways can easily cost $75 or more. If that CRT is a year-old 17" model, you"re probably better off spending $100 to $200 for a new 17" or 19" CRT than paying $75 in shipping to have the old one repaired. CRTs have many components, all of which age together. Fixing one is no guarantee that another won"t fail shortly. In fact, that happens more often than not in our experience.

Never disassemble a CRT. At best, you may destroy the CRT. At worst, it may destroy you. Like televisions, CRTs use extremely high voltages internally, and have large capacitors that store that energy for days or even weeks after the CRT is unplugged. Robert once literally burned a screwdriver in half when working inside a color television that had been unplugged for several days. Also, the large, fragile tube may implode, scattering glass fragments like a hand grenade. People who repair CRTs and televisions for a living treat them with great respect, and so should you. If you must repair a CRT, take it to someone who knows what they are doing. You have been warned.

Check the obvious things first. Verify that the CRT is plugged in (and that the receptacle has power), the video cable is connected to the video card, the computer and CRT are turned on, and the brightness and contrast settings are set to the middle of their range. If none of these steps solves the problem, your CRT, video card, or video cable may be bad. Check the suspect CRT on a known-good system or a known-good CRT on the problem system.

CRTs contain multiple filaments, which can be broken, or gas may have leaked into the vacuum inside the CRT. CRTs damaged this way are unrepairable without specialist equipment. With the display open. check if all three filaments are glowing bright orange. Excessive redness or purple arcing signifies gas has leaked in. There may also be an internal short inside the CRT, which is also unfixable without specialist equipment.

If you have ACPI or APM power management enabled, it may be causing the problem. Some systems simply refuse to wake up once power management puts them to sleep. We have seen such systems survive a hardware reset without restoring power to the CRT. To verify this problem, turn off power to the system and CRT and then turn them back on. If the CRT then displays an image, check the power management settings in your BIOS and operating system and disable them if necessary.

Catastrophic CRT failure is imminent. The noises are caused by high-voltage arcing, and the smell is caused by burning insulation. Unplug the CRT from the wall before it catches fire, literally.

There are two likely causes. First, you may be driving the CRT beyond its design limits. Some CRTs display a usable image at resolutions and/or refresh rates higher than they are designed to use, but under such abuse the expected life of the CRT is shortened dramatically, perhaps to minutes. To correct this problem, change video settings to values that are within the CRT"s design specifications. Second, the power receptacle may be supplying voltage lower than the CRT requires. To correct this problem, connect the CRT to a different circuit or to a UPS or power conditioner that supplies standard voltage regardless of input voltage.

This is usually a minor hardware problem. The most likely cause is that the signal cable is not connected tightly to the CRT and/or video card, causing some pins to make contact intermittently or not at all. Verify that no pins are loose, bent, or missing on the cable or the connectors on the CRT and video card, and then tighten the cable at both ends, If that doesn"t fix the problem, open the computer, remove the video card, and reseat it fully.

In elderly systems, another possible cause is that some hardware DVD decoder cards "steal" one color (usually magenta) and use it to map the DVD video signal onto the standard video signal. Remove the DVD decoder card. If your video adapter includes hardware DVD support, or if you are upgrading to such an adapter, you don"t need a DVD decoder card.

The most likely cause is that the CRT is receiving inadequate power. Connect it to a different circuit or to a backup power supply that provides correct voltage regardless of fluctuations in mains voltage.

The most likely cause is that the refresh rate is set too low. Change the refresh rate to at least 75 Hz. Flicker also results from interaction with fluorescent lights, which operate on 60 Hz AC and can heterodyne visually with the CRT. This can occur at 60 Hz (which is far too low a refresh rate anyway), but can also occur at 120 Hz. If you"re running at 120 Hz refresh and experience flicker, either use incandescent lighting or reset the refresh rate to something other than 120 Hz.

The video card settings are likely outside the range supported by the CRT, particularly if you have just installed the CRT or have just changed video settings. To verify this, restart the system in Safe Mode (press F8 during boot to display the Windows boot menu and choose Safe Mode). If the system displays a VGA image properly, change your display settings to something supported by the CRT.

Most modern CRTs can display signals at many different scan frequencies, but this doesn"t mean that the CRT will necessarily automatically display different signals full-screen and properly aligned. Use the CRT controls to adjust the size and alignment of the image.

Depending on the CRT, video card, and video settings, this may be normal behavior, adjustable using the CRT controls. If the distortion is beyond the ability of the controls to correct, the problem may be with the video card, the CRT, or the driver. First try changing video settings. If the problem persists at several settings, move that CRT to a different system (or use a different video card) to determine whether the problem is caused by the CRT or video card. Repair or replace the faulty component.

This is usually caused by RF interference from another electrical or electronic device, particularly one that contains a motor. Make sure such devices are at least three feet from the CRT. Note that such interference can sometimes penetrate typical residential and office walls, so if the CRT is close to a wall, check the other side. Such image problems can also be caused by interference carried by the power line or by voltage variations in the AC power supply. To eliminate interference, plug the CRT into a surge protector. Better still, plug it into a UPS or power conditioner that supplies clean power at a constant voltage.

This problem may also be caused by using a video cable that is too long or of poor quality or by using a poor-quality KVM switch (keyboard/video/mouse switch). Manual KVM switches are particularly problematic.

The CRT may need to be degaussed. A CRT that sits in one position for months or years can be affected even by the earth"s very weak magnetic field, causing distortion and other display problems. Exposing a CRT to a strong magnetic field, such as unshielded speakers, can cause more extreme image problems. Many modern CRTs degauss themselves automatically each time you cycle the power, but some have a manual degauss button that you must remember to use. If your CRT has a manual degauss button, use it every month or two. The degaussing circuitry in some CRTs has limited power. We have seen CRTs that were accidentally exposed to strong magnetic fields, resulting in a badly distorted image. Built-in degaussing did little or nothing. In that case, you can sometimes fix the problem by using a separate degaussing coil, available at RadioShack and similar stores for a few dollars. We have, however, seen CRTs that were so badly "magnet burned" that even a standalone degaussing coil could not completely eliminate the problem. The moral is to keep magnets away from your CRT, including those in speakers that are not video-shielded.

An incorrect yoke may have been attached to the CRT. Unless you have a lot of spare time on your hands, this is usually not worth fixing. Replace the display.

You may have a weak picture tube. Without specialist equipment, this is usually unfixable. You could try a CRT rejuvenator as a last resort, but this may fix or kill your CRT permanently.

If your LCD displays no image at all and you are certain that it is receiving power and video signal, first adjust the brightness and contrast settings to higher values. If that doesn"t work, turn off the system and LCD, disconnect the LCD signal cable from the computer, and turn on the LCD by itself. It should display some sort of initialization screen, if only perhaps a "No video signal" message. If nothing lights up and no message is displayed, contact technical support for your LCD manufacturer. If your LCD supports multiple inputs, you may need to press a button to cycle through the inputs and set it to the correct one.

Unlike CRTs, where increasing the refresh rate always reduces flicker, LCDs have an optimal refresh rate that may be lower than the highest refresh rate supported. For example, a 17" LCD operating in analog mode may support 60 Hz and 75 Hz refresh. Although it sounds counterintuitive to anyone whose experience has been with CRTs, reducing the refresh rate from 75 Hz to 60 Hz may improve image stability. Check the manual to determine the optimum refresh rate for your LCD, and set your video adapter to use that rate.

First, try setting the optimal refresh rate as described above. If that doesn"t solve the problem and you are using an analog interface, there are several possible causes, most of which are due to poor synchronization between the video adapter clock and the display clock, or to phase problems. If your LCD has an auto-adjust, auto-setup, or auto-synchronize option, try using that first. If not, try adjusting the phase and/or clock settings manually until you have a usable image. If you are using an extension or longer than standard video cable, try connecting the standard video cable that was supplied with the display. Long analog video cables exacerbate sync problems. Also, if you are using a KVM switch, particularly a manual model, try instead connecting the LCD directly to the video adapter. Many LCDs are difficult or impossible to synchronize if you use a KVM switch. If you are unable to achieve proper synchronization, try connecting the LCD to a different computer. If you are unable to achieve synchronization on the second computer, the LCD may be defective. Finally, note that some models of video adapter simply don"t function well with some models of LCD.

If the screen is displaying a full, stable image, but that image is of poor quality, first verify that the display is not connected through a KVM switch or using an extension cable. If so, connect the display directly to the video adapter using the standard cable. If that is already the case, adjust the brightness, contrast, and focus controls. If you are unable to get a proper image using these controls, the problem is most likely a clock or phase mismatch, which you can cure by taking the steps described in the preceding item.

The best way to adjust clock and phase is to use auto-adjust first. Check the utility and driver CD that came with the monitor. It may have a wizard or at least the appropriate background screens to use while adjusting phase and clock settings. If not, go to the Windows Start menu and select Shutdown. When the screen goes gray and the Windows Shutdown dialog appears, leave that dialog onscreen, but ignore it. Use the gray screen to adjust clock and phase manually. Any problems with clock and phase and any changes you make to the clock and phase settings are clearly evident on the gray screen.

Always adjust clock first. Clock is usually not a problem if you have used the auto-adjust feature of your monitor, but if you do have clock problems they will be evident as large vertical bars on your screen. Tweak the clock setting until those bars disappear. Then adjust phase. Phase problems are evident as thin black lines running horizontally across the screen. Adjust phase until the lines disappear or are minimized.

Not all analog video cards synchronize perfectly with flat panels. The gray Shutdown screen exaggerates the problem, so don"t worry if very tiny movements are visible after you"ve adjusted clock and phase as well as possible. After you"ve set the clock and phase controls for the best image possible on the gray screen, cancel Shutdown and the image should be optimized.

Your video card is supplying a video signal at a bandwidth that is above or below the ability of your LCD to display. Reset your video parameters to be within the range supported by the LCD. If necessary, temporarily connect a different display or start Windows in Safe Mode and choose standard VGA in order to change video settings.

This occurs when you run an LCD at other than its native resolution. For example, if you have a 19" LCD with native 1280x1024 resolution but have your display adapter set to 1024x768, your LCD attempts to display those 1024x768 pixels at full screen size, which physically corresponds to 1280x1024 pixels. The pixel extrapolation needed to fill the screen with the smaller image results in artifacts such as blocky or poorly rendered text, jaggy lines, and so on. Either set your video adapter to display the native resolution of the LCD, or set your LCD to display the lower-resolution image without stretching the display (a feature sometimes referred to as display expansion), so that pixels are displayed 1:1, which results in the lower resolution using less than the entire screen.

This is a characteristic of LCDs, particularly older and inexpensive models, caused by defective pixels. Manufacturers set a threshold number below which they consider a display acceptable. That number varies with the manufacturer, the model, and the size of the display, but is typically in the range of 5 to 10 pixels. (Better LCDs nowadays usually have zero dead pixels.) Nothing can be done to fix defective pixels. Manufacturers will not replace LCDs under warranty unless the number of defective pixels exceeds the threshold number.

Some people claim that leaving the unit powered off for a day or two will "erase" a persistent after-image. Others suggest leaving a neutral gray screen (like the one used for phase adjustment) up on the screen to "equalize" the display. I dunno. FWIW, I"ve seen this problem on older Samsung panels but never on the Sony or NEC/LaCie panels I use.

Again, this is a characteristic of LCDs, particularly older and inexpensive models. The after-image occurs when the display has had the same image in one place for a long time. The after-image may persist even after you turn the display off.

Transistor-based pixels in an LCD respond more slowly than the phosphors in a CRT. The least-expensive LCDs exhibit this problem even with slow image movement, as when you drag a window. Better LCDs handle moderately fast image movement without ghosting, but exhibit the problem on fast-motion video. The best LCDs handle even fast-motion video and 3D gaming very well. The only solution to this problem is to upgrade to an LCD with faster response time.

Use the brightness control to increase image brightness. If you have set brightness to maximum and the image is still too dim, contact the display manufacturer. The CCRTs used to backlight the screen have a finite lifetime and may begin to dim as they near the end of their life.

If one or more horizontal and/or vertical lines appear on the display, first power-reset the computer and display. If the lines persist, run the auto-setup function of your display. If that does not solve the problem, power the system and display down, remove the video cable, and verify that the video plugs and jacks on both computer and display ends do not have broken or bent pins. Even if all appears correct, try a different video cable. If the problem persists, contact the display manufacturer.

With your ever-growing collection of electronic devices, perhaps it seems your home never has enough power outlets. Power strips and their more elaborate siblings, surge protectors, offer an easy solution: one plug in the wall, many outlets for your devices. But wait! There"s more to these simple-seeming products than meets the eye.

Adding additional AC outlets and USB charging ports is incredibly useful, and often vital. Don"t waste money on the wrong one, however. Here"s everything you need to know about power strips and surge protectors.

Typically, power strips are cheap, multioutlet products that are merely an expansion of a wall outlet. They"re usually small and thin, sometimes fitting directly onto the outlet itself. They usually have a circuit breaker (on/off switch) of some sort, but most don"t offer any real "protection" from electrical issues. Some might have the barest level of protection, but they"re all pretty much just like plugging into the wall directly.

Surge protectors are relatively cheap too, but unlike power strips they offer some level of protection. As their name suggests, surge protectors protect your products from power surges at the expense of itself. But more on that in a moment. How much they do this, and how well varies considerably. They"re usually a bit more elaborate, and often bigger, than a simple power strip, though not always.

Surge protectors offer protection in units called joules. Generally, the more joules the better, as this means the device can handle one large surge, or multiple smaller surges, before your gear is in danger. Over time, the parts inside the protector wear down, reducing its effectiveness.

Unfortunately, there"s no way to know how much protection a device has left, or if the initial rating is even accurate. Buying from a reputable company, and one that includes a warranty, is a good idea.

Some surge protectors offer a warranty (up to a certain amount) on the gear connected to the protector. For example, in the US, certain Belkin models have up to $300,000 in connected equipment warranty, and states: "Belkin Components will repair or replace, at its option, any equipment which is damaged by a transient voltage surge/spike or lightning strike, (an "Occurrence"), while properly connected through a Belkin Surge Protector to a properly wired AC power line with protective ground."

You"ll probably never need it, but it certainly doesn"t hurt to have it. Keep in mind, however, that just because the warranty exists doesn"t mean you"ll ever see a dime from it. Note in that Belkin quote the term "at its option." That means they"ll come up with any reason not to cover your claim. So don"t use this as a replacement for home or renter"s insurance.

You"re always going to need more outlets. You"ll undoubtedly add more gear, without necessarily getting rid of your current gear. I"m not saying that if you think you need four outlets, you should get 12 -- but at least six is probably a good investment.

Most modern devices use "wall warts" -- plugs that convert AC power into DC power and look like little boxes with electrical prongs sticking out. Consider getting a surge protector with wider spacing between sockets, or sockets that can be rotated or moved, to accommodate chunky plugs.

Many surge protectors come with USB connections, so you can charge your mobile devices without having to use their wall warts. Handy, for sure, but check what the output amp rating is. Generally, this is either 1 or 2 amps (often labeled 1A or 2A). This is how much flow you can get through the pipe, so to speak. You"ll want at least 2 amps for quicker charging.

Most modern phones have the ability to fast-charge, but you"ll need to use their wall warts for that. If you don"t need to quickly charge them, though, these lower power ports will work just fine.

While not offering much protection, a portable power strip might prevent marital friction, and/or invoke bliss from travel companions. Most hotels and hostels have few accessible outlets, yet everyone has multiple devices that need recharging. Most portable power strips add two to three additional outlets, plus offer direct USB charging (see No. 8, above).

Remember the joule rating we discussed earlier? This is just the initial rating. This gets lower over time. In other words, surge protectors wear out. Some will give you a warning or shut off when their protection drops below a safe level. Many will just keep working, without protection, and you won"t know it until a power spike damages your gear. If you know you"ve had a serious electrical event (like lightning blew out a transformer down the street), it"s probably worth replacing your surge protector just in case.

Most companies that sell surge protectors say they need to be replaced every three to five years. Sure, they"re motivated to have you buy them more often, but with many models under $50, this isn"t an extreme cost.

There is no reason not to get a surge protector over a simple power strip. If you live in an area with lots of thunderstorms, your gear is probably more likely to experience power surges. Even if you live in the desert, your AC or refrigerator could kick power spikes back down the lines to your AV gear. Either way, some extra protection for your gear is absolutely worth the small difference in price between simple power strips and surge protectors.

In the United States, National Electric Code article 210-19 FPN No. 4. suggests a 5% maximum combined voltage drop on the feeder and branch circuits to the furthest outlet "will provide reasonable efficiency of operation." The Canadian electrical code also requires no more than a 5% drop between the meter and outlet. Applying the 5% tolerance gives a nominal 120V range of 114V to 126V.

Yes, a power conditioner will stabilize the voltage from a generator. However, it will not convert the modified sine wave produced by some generators to pure sine wave, making those generators unsuitable for sensitive electronics.

Yes, but not with the printer itself. Printers and copiers use a hot roller called a fuser unit to bind ink toner to the paper as it passes through the printer. Periodically, the printer needs to reheat the fuser unit to the required temperature, and this requires a lot of electricity. To prevent a power sag (under-voltage) from impacting computers and other sensitive equipment on the same circuit as the printer, use a power conditioner with Automatic Voltage Regulation (AVR).

Connecting a printer to a line conditioner may prevent the printer from getting the voltage it needs. A better approach would be to have a qualified electrician check the capacity of the existing line and add a separate circuit for the printer if necessary.

A power or voltage spike is a sudden increase in voltage, ranging from a few hundred volts to tens of thousands and lasting between 1 and 30 microseconds. A power surge is like a spike but lasts longer. Voltage fluctuations are normal and do not typically harm equipment connected to an outlet. Over- or under-voltages occur when the voltage reaching powered devices falls out of the normal service range.

As a power conditioner corrects high or low input voltage, it will make a gentle clicking sound. The frequency of the clicking will depend on the quality of the utility power in your area. The clicking is normal, and no action is required on your part.

A power conditioner can potentially improve sound quality by providing a cleaner and more stable power supply to audio equipment. Power fluctuations and electrical noise can interfere with the performance of audio equipment, leading to degradation in sound quality. By conditioning the power, a power conditioner can reduce the amount of electrical noise and provide a stable voltage, which can result in improved sound quality.

However, it is important to note that the effect of a power conditioner on sound quality can vary depending on the equipment and the specific electrical problems being addressed. In some cases, the improvement in sound quality may be minimal or not noticeable, while in other cases it can be significant.

A power conditioner is an electrical device that improves the quality of the power supplied to an electrical load by regulating voltage, reducing noise, and filtering out electrical disturbances. The goal of a power conditioner is to protect sensitive electronic equipment from damage caused by power fluctuations and electrical noise.

A surge protector, on the other hand, is specifically designed to protect electronic equipment from damage caused by power surges and spikes. It accomplishes this by diverting excess voltage away from connected equipment.

Some power conditioners include surge protection as part of their functionality, effectively combining the two functions into a single device. In these cases, the power conditioner can improve the quality of the power supply while also providing protection against power surges and spikes.

If improved sound quality is your primary goal, an isolation transformer is the best choice. Microphones, instruments and amplifiers can pick up unwanted hums or buzzes if they are plugged into the same circuit as items such as fluorescent lights, air conditioners and dimmer switches. If your band is playing in a bar, even the bartender"s blender is a potential source of interference!

An isolation transformer uses two coils of copper wire, wound so that the primary coil connected to incoming AC power induces a current in the secondary coil powering connected devices. Since there is no direct connection between the coils, musical instruments and recording equipment attached to the secondary coil are isolated from audio frequency noise on the power line.

So in this ultimate guide, we’re going to solve that problem once-and-for-all by removing all the jargon and giving you just the straight forward facts.

Quite often, potential buyers fair understand the difference between these two similar tools. Many will even mistake one for the other, and end up buying the wrong one.

Uninterruptible Power Supplies – contain a backup battery that provides several minutes of power in the event of a blackout, and are typically used with computers to protect sensitive data by allowing enough time for proper shutdown.

While this method works well for most of the time, the switching process does cause a momentary power lapse, which is dangerous for highly-sensitive equipment.

So unlike the standby UPS which engages only when there’s a problem…the online UPS continuously filters power through the battery before sending it to your computer.

However…to increase energy efficiency, a similar online method known as delta conversion also exists…which delivers a portion of the power directly to the computer, rather than through the battery.

The standby UPS has trouble handling these sort of interruptions because they must repeatedly switch back and forth between AC and battery power with each dip.

The Online UPS on the other hand, is great at handling brownouts, as they’re able to maintain a consistent voltage by continuously running off battery power. But as you know…they’re expensive.

Using a special type of transformer, it varies output voltage in response to momentary power fluctuations. So when the power dips, the transformer is still able maintain a stable output without switching over to battery power.

However, other factors affect run-time as well, such as the battery condition, and load required to power all connected devices. So actual run times may still stretch far outside that range.

Performance Monitoring – built-in displays that show real-time stats including run-time, battery health, etc. Software versions also exist, some smart enough to shut down your computer automatically when battery reserves drop too low.

The Integrity Pro UPS Series is designed from the ground up to incorporate itself flawlessly and reliably into any environment. It is engineered to provide constant, uninterrupted power for sophisticated computer loads in medical, retail, diagnostic, and office I.T. settings. Ensuring your electronic systems are fully protected with our industry-leading power quality technology.

For decades, traditional audio/video components were simple analog devices designed to easily weather power outages of well over two seconds. Later, as computer and microprocessor based components gained in popularity, their extraordinary sensitivity to even a fraction of a second’s power loss was managed with traditional UPS (uninterruptible power supply) technology.

Unfortunately, these units were solely designed for the I.T. professional. Though they included many technologies and features appropriate to that application, they fell short for premium audio/video components. Though many of these manufacturers later recognized the ever-emerging professional audio/video, broadcast, and home theater market, their lack of experience led merely to a re-tooled chassis. These hastily produced UPS devices lacked the technologies necessary to truly optimize protection, performance, and control for today’s audio video components.

The Furman F1500-UPS more than fills this void, and offers your system unparalleled battery back-up technology, created from the ground up to meet the exacting demands of the world’s most sensitive audio, video and control systems!

Typical UPS systems feature antiquated surge suppression technologies that can cause as much damage and annoying lock-ups as they attempt to prevent. Only Furman offers battery back-up with our road-proven SMP non-sacrificial, zero ground contamination surge suppression technology and EVS Extreme Voltage Shutdown. After all, the most robust battery cannot function if the accompanying circuits are damaged. With Furman’s F1500-UPS, you can expect years of trouble free operation.

Though many control devices are relatively immune to moderate levels of AC line noise, today’s more sensitive devices (such as DLP projectors and line-level signal processors) certainly are not. High-definition technologies have pushed resolution to levels so extreme that virtually any AC noise capable of coupling with your system’s signal will distort, mask, or destroy the performance advantages we all strive so hard to capture and reproduce. Once again, the F1500-UPS is different. While other UPS devices feature AC line filters suitable for an IT closet, only Furman employs our exclusive Linear Filtering Technology (LiFT) to four discrete isolated outlet banks. This advanced noise filtering technology assures that today’s ultra-wide dynamic range is maintained as it must be – pristine. Remember, less AC noise equals greater content, greater resolution, and higher definition.

The F1500-UPS provides True Sine Wave output when in battery backup mode, ensuring the utmost reliability to all connected equipment while running on battery power.

At 1500VA, the F1500-UPS provides substantial backup time for most critical digital A/V components (see runtime chart). If more runtime is needed, 1500VA battery packs (BATT1500E-EXT) may be daisy chained to double, triple, and further increase runtime as the application demands.

Audio/video systems can vary greatly in their size and components, and as such, flexibility is needed in determining how a battery backup solution should function under different circumstances. Because of this, Furman has provided open source RS-232 control over four independent AC outlet banks, with a wide range of features to interface with an existing control unit. Dual programmable IR control allows the unit to send a shut down command to remote components in the event of a blackout – no more expensive projector bulbs to replace in the event of a blackout. Optional TCP/IP control (separate interface card, available Q4), offers remote control over any Internet connection via a truly plug-and-play, hosted, web-based graphical user interface, with full remote control and power monitoring functionality.

Given the nature of battery backup technology, high-current audio and video components such as power amplifiers, powered subwoofers, and high-wattage displays are not recommended for use with the F1500-UPS. Not only will these components drain battery power quite rapidly, line impedance will be raised due to the F1500-UPS’s (or any) AVR and AC to DC inverter, which can induce current compression and noticeably diminish performance with high-current A/V equipment. The following components are ideal for use with the F1500-UPS:

For power management of other components, Furman recommends Classic or Prestige Series Power Conditioners. For high-current components such as power amplifiers and powered subwoofers, solutions featuring Furman’s exclusive Power Factor Technology are ideal.

In testing, this surge protector was one of the best at preventing extra voltage from reaching its outlets. It also safely stops all power once the protection wears out, and it has 12 AC outlets plus coaxial and phone ports.

If you want a surge protector for your home office or entertainment setup, the Tripp Lite Protect It 12-Outlet Surge Protector TLP1208TELTV is your best choice. It has a critical auto-shutoff feature, more than enough outlets to keep all your gadgets powered, and both coaxial and telephone connectors. It offers great protection against household surges that come from other equipment in your home or fluctuations from the power company. Plus, it has a generous 8-foot cord, and it feels sturdy and robust.

For light-duty powering, such as under a nightstand or end table, the Accell Power Air is the way to go to protect gadgets such as phones, tablets, or alarm clocks from surges. It offers two USB ports and six AC outlets in a round package that’s smaller than a dinner plate. The USB ports put out a combined 2.4 amps, enough to charge one smartphone or tablet at a high speed or two devices at low speeds. The circular outlet layout makes the Power Air usable with a variety of plug sizes. Its 6-foot cord is 2 feet shorter than that of the Tripp Lite 12-outlet model but should still be plenty long for most people. The Power Air performed almost as well as our top pick against individual surges, though it might not hold up to as many surges over its lifetime given its lower joule rating (which describes roughly how much energy it can absorb before it dies—the company estimates it’ll withstand about 1,080 joules of use, whereas many larger models are built to handle more than 2,000 joules).

Tripp Lite’s three-outlet SK30USB has an auto-shutoff feature and offers almost as much surge protection as full-size models. Plus, it has two 2.1-amp USB ports.

The Tripp Lite Protect It 3-Outlet Surge Protector SK30USB offers the portability of our favorite small power strips for travel but with even more protection. It has an auto-shutoff mechanism, making it one of the few three-outlet options we’ve found that will disconnect the power when the surge protection wears out. In addition to the three AC outlets, it comes equipped with two USB ports that offer a combined 2.1 amps to charge a phone, a tablet, or a couple of low-power devices. It performs well compared with other small options we’ve tested, blocking almost as many volts as larger models. In contrast to many comparable models, its compact size, grounded (three-prong) plug, and optional screw in the center of the unit help keep it firmly attached to the wall outlet, which is important for preventing electrical fires or shocks. We’d choose the SK30USB for protecting a few small household appliances—say, an essential oil diffuser, a Nintendo Switch dock, and a coffee grinder—and a couple of smartphones, or even for tossing in a carry-on when we’re traveling.

Tripp Lite’s eight-outlet TLP825 has a 25-foot cord, which is three to four times the length of most surge protector cords. It has fewer outlets than our top pick and no extra ports, but it performed almost as well in our surge tests.

With a cord measuring 25 feet, the Tripp Lite Protect It 8-Outlet Surge Protector TLP825 has the longest cord of any of our picks, making it the ideal choice for a garage, a basement, or any room where wall outlets are few and far between. It performed about as well as Tripp Lite’s 12-outlet TLP1208TELTV (and better than Accell’s Power Air and Tripp Lite’s three-outlet SK30USB) in our surge tests. Since it’s unsafe to plug a surge protector into an extension cord or to daisy-chain multiple surge protectors together, you should get this model if the devices you want to protect are more than 8 feet away from an outlet. It has four fewer outlets than our top pick and no additional ports (coaxial, phone, or USB), but that’s a small sacrifice if you need the extra cord length.

Overkill unless you have high-end home theater, office, or media equipment, this unit knocked down surges better than any other model we tried, including surge eliminators costing twice as much.

Our top pick will protect most equipment in most cases. But the Furman Power Station 8 (PST-8) goes further, providing the best surge suppression of any model we tested—enough to give owners of high-end electronics peace of mind. It turned a 5,000-volt surge into just 40 volts, thanks in part to a shutdown circuit that turns off all power when a surge is detected. The PST-8 actually let less voltage through in our tests than high-end series mode surge eliminators that can cost hundreds more. But common equipment, such as a computer monitor, will be fine protected by one of our less expensive picks, so this model is best for people who insist on extra protection for particularly precious gear. Plus, it has a sturdy aluminum body and an 8-foot cord.

The new Venus (SBP) Plus Series of uninterruptible power supply with Transformer-Based Filter (TBF™) offers high performance and comprehensive power protection. This advanced power protection solution offers battery backup plus the ability to regulate voltage fluctuations through an integrated Automatic Voltage Regulator.
