Furman P-1800 AR Advanced Level Voltage Regularor/Power Conditioner, 15 Amp, Regulates 97-137 Volt Input Range to 120 Volt Output

I am using this to protect the electronics in my living room: the TV, Amplifier, DVR, laptop computers, etc.Install is easy. No need to read the manual. Give it power, plug in your devices, and let it run. By default, the display on the front shows voltage. I changed mine to amps, a single button click, and I reduced the brightness to its minimum, press and hold. When the TV, Amp, and speakers are running, it shows 5 amps, else 1 amp (router, DVR, etc.). I like this view. If I accidentally leave the TV amplifier on, I can see it immediately in the readout.As luck would have it (or not), 4 weeks after installing the Furman, the transformer outside of our house exploded. As I understand it, these transformers have internal backups, so as one circuit blows out, another takes over, until finally all 4 of them are gone and you lose power for good. As each of the circuits blows, the power is restored momentarily, only to go again. So what happened?Items that weren't protected, like my electric stove and the ceiling lights, flicked on and off rapidly for 30 seconds as the transformer went through its death throes.What the Furman did was interesting. As soon as the voltage went too far out of range (I am presuming it alternated between low and high), it cut power to the outlets, protecting them from the voltage swings. While the stove and the lights were flicking on and off, everything protected by the Furman was safely off.Unlike other voltage regulators (I own an APC LE1200 and a Tripp Lite LC1800), this one doesn't click as it shifts the voltage back into range.Build quality appears good, and the unit runs cool to the touch.Although the P-1800 is designed to be rack mounted, i run mine on a shelf in the entertainment center, which works fine.I also use a Furman AC-215A to protect my fridge. The AC-215 is a smaller unit with two outlets, and is light enough to sit on top of the fridge. Again, appears very well made.I should also note that I did not notice any difference in picture quality or sound due to the cleaner power. That wasn't why I bought the unit, it was purely for protection.A final note. Several years ago, I used an APC Back-Ups Uninterruptible Power Supply. A storm hit, and fried my $2,000 server that was supposedly protected by the APC. I don't buy UPS units any more. I have found that it is safer to let devices power down than to provide DC converted power as the battery backed systems do. Better to have no power, than bad power.

I have this installed in equipment rack for live band P.A. It gives me peace of mind as many different locales have many different potential power quality issues. It is very, very heavy and so I have it bottom mounted, no lights so no reason to mount in top-most rack position. Will not fit a shallow rack and I will be devising a way to support back of unit on rear rack rails due to weight concerns. Furman does not include any provisions for doing so which would make me 100% comfortable hauling this around to gigs. I do not have any test equipment to verify capabilities of power conditioning ability, but Furman is the standard and this unit is extremely robust.

gran equipo para dar confianza en la corriente que llega a los equipos sensibles. estoy muy contento

This unit is doing what I bought it to do.Keeping the power to my studio gear supplied and protected.I don't have worries anymore about the incoming power as the unit is wrangling it and I've never seen my downline furman so happy with the power it's getting.Plus aesthetically it's a sleek looking piece of gear.It aint cheap, bit in a critical recording environment in my home studio you can't go wrong buying this.One less thing to think about while creating !!

This device is whisper quiet and cost more than the Panamex but is far better in my view. Voltage correction seems to start about 3.5 from 120. I thought it corrected regardless, like 119.5 to 120.0 but it does not you need to be off a bit before it kicks in. but once it does the output is spot on at 120.0 (at least for the ranges I have experienced with input as low as 112). In contrast the Panamex will not correct until you are at 115 or 125, and it buzzes when it is turned on and when it corrects voltage and when it just sits there sometimes. And it won't correct to precisely 120.0 it often over-corrected to 122 or 123. I had two Panamexs for a short period returned them, have two Furmans, now. And there is no audible sound that comes out of the Furman.

This is an excellent overvolt and undervolt protector for all electronic gear, including vintage tube equipment

Does what it is made to do: regulates crappy voltage. In my practice studio it goes from 103 to 117 volts and is never steady. The voltage regulator helps to keep the sound of my guitar always the same, it prevents my tube rack amp to keep the same sound no matter where I play.

I can’t trust Furman any longer. My Furman AR-1215 is not functioning. It’s in the shop for three months because Furman no longer carries parts. If you would look at my unit, it doesn’t even have a scratch on it and I only used it on gigs for my computer and a few keyboards. I bought this thing because bad power caused a malfunction on one of my keyboards. This board was old but I was still able to get it fixed. I called Furman and was told to just go buy the new 1800 model. I didn’t need anyone to tell me I can buy a new one. Honestly, I don’t trust the brand any longer. I have three other Furman power conditioning units. I’m not opposed to buying a new voltage regulator. C’mon man, at least offer a schematic to see if my repair person might be able to make this thing work. I’m sure Furman didn’t make the components. Didn’t mean to ramble, but to take something that I paid over $700.00 for and use it as a boat anchor because they choose not to carry replacement parts. I can get my 35 year old Yamaha DX7 repaired. I’m extremely disappointed to say the least. On a positive note, I felt very comfortable knowing that my equipment was protected when it did work. What’s going to happen if I do buy the 1800 and ten years down the road, will I have 2 boat anchors?
