The APC LE1200 prevents this damage. It clicks on and returns voltage levels back to around 120V at a level high enough that your electronics don't get damage before they are protected (what's the point of protection that only helps once the damage is done?). I know it's working because I can hear it click on, and return power to the right levels even as my house voltage sits at 106-108V (confirmed by the voltage meter in my Panamax).
I'm so impressed with the performance of this unit in my home theater that I bought 2 more, one to protect my computer (it installs between the UPS and the wall to protect the computer and the UPS), and one for my plasma TV (because it's located away from my HT equipment). At $50 a piece, this thing is a no brainer. A quality UPS is 3-5x as much and still doesn't protect your equipment as well. And it can burn out. The LE1200 has little chance of burning out, so for equipment that doesn't need battery backup, or even to feed a UPS, this product is the way to go.
Construction is cheap. Amazon needs to ship these in bigger boxes with packing material for cushion...MY FIRST ONE CAME IN WITHOUT PACKING MATERIAL AND THUS DAMAGED DURING SHIPPING. My replacement one was undamaged but packed the same way without cushion, the only difference is the shipment went via expedited, so less trans loading and handling when moved. Amazon customer service was VERY HELPFUL in arranging this expedited shipping for me, at no extra cost.
I made my review about the packaging with Amazon, and they acknowledged this. Hopefully will help others.
This product is not a UPS with a battery, strictly line voltage regulation. It does have surge protection rated at 702 joules.
***There seems to be confusion of when this unit will regulate voltage, and one must read the specifications to understand this.
For most in the US 120 volts is the norm, so when this unit is set to that, it has a -12% to +6% range around the center voltage of 120 volts according to the specs. Most electronic device power supplies are designed to handle the range this unit regulates to. The response time this reacts to any voltage fluctuations is acceptable to (under 2 AC cycles)
THAT MEANS...When set to 120 on the back and your incoming line voltage drops below 105 volts this will activate the transformer to step up the voltage back to around ~120. If you have an over voltage, it will not activate the transformer until the incoming voltage goes above 127.2 volts to step it back down.
You own some serious vintage tube hi-fi gear. Hmmm, you keep blowing rectifiers, or fuses, or even power tubes. Then you slap your digital VOM meter in the wall socket and discover that the electric company is delivering 122-130 VAC! Golly! You always thought it was supposed to be 110 VAC or maybe 117 VAC? Gee, your great vintage tube gear was designed to run on 110-117 VAC, what's going on here?! Now you know why the cathode pin on your amp's 12AU7 phase splitter is running 25 volts too high, -and why the plate voltages from your precious Mullard EL34 power tubes are running at 435 instead of 415 VDC. And why the 5AR4 rectifier is running at almost 550 volts -well past it's limit of about 520 VAC. And, all those expensive new electrolytics that are rated at only 450 VDC, oooohhhh dis hurts!!!
Don't feel bad, I blew 2 rectifiers and 2 sets of Winged C power tubes (8 matched tubes!) before I figured it out. I was lucky. I designed and built my own unit and I over-rated most components. But tube ratings are not flexible!
Or you own a computer or home entertainment system. The PC or perhaps the DVD player mysteriously blew out after a storm -or perhaps just blew out for no reason... or the lights flickered, perhaps -whatever. Your top-of-the-line "Surge Protector" did absolutely NOTHING! You remember, -of course, you do. It was the one that was waaay more expensive, and the pushy salesman talked you into buying it so as to "protect your investment". It did not do this. Alas, you are crying. Your $2000 Blue Ray player is fried and maybe your $3000 Marantz A/V digital receiver. Have no fear.Read more ›
