APC UPS, 1500VA Sine Wave UPS Battery Backup & Surge Protector, BR1500MS2, Backup Battery with AVR, (2) USB Charger Ports, Back-UPS Pro Uninterruptible Power Supply

Es un excelente NoBreak que debes de tener en la casa o la oficina. De inicio la batería viene desconectada (por seguridad al transportarse) por lo que deberás abrirlo y conectar la batería, es muy fácil y tiene las instrucciones con etiquetas amarillas que te guiarán paso a paso. - El display no se puede apagar y tampoco se puede reducir el brillo. - Silencioso No es. Hace un "ruidito" que indica que está funcionando que Si es bastante audible, por lo que hay que lidiar con esto. + La bateria recargada por completo, si cubre al menos 40 min. (tengo conectado los servicios del ISP, NAS y un sistema de Alarma y todo funcionó correcto cuando se interrumpió el servicio de energía) + Cuando hay una sobrecarga, la contiene y se apaga por seguridad (esto me pasó cuando registró una descarga porque un auto choco en el poste de energía) + Mejor que cualquier producto TrippLite ;) Precio competitivo !

My 3rd purchase of this. I use 2 at once but one of them just saved my $6000 PC. Lightning struck right next to my house, so close that it shook the house. I was on my PC when it happened and the current actually came through my mouse and shocked me. I thought I lost my PC for sure. When the power came back on, the APC was fried... but my PC and everything else connected to it still worked. We lost a couple of other electronics in the house due to the strike, but everything connected to both of my APC's were protected. Paid for itself

tHIS IS THE SECOND UNNIT i HAVE PURCHASED, THE FIRST IS NOW IN SERVICEE FOR 4 YEARS AND BACKS UP MY COMPUTER EQUIPMENT AND WITH THIS RECORD I PURCHASED TGIS ONE TO BACK UP MY HOME THEATER SYSTEM, I WENT FOR THE WINNER.

excelente producto.cuando se va la luz entra muy rapido que no permite que una panatalla de 77 pulgas se apague protege muy bien los equipos

I have used APC UPS of various models for many, many years. They have always performed as expected. I currently have the Back-UPS Pro BR1500MS2 and it works perfectly. I'm writing this review not so much so about the UPS, but more for information on what to expect if using this UPS with a portable generator. I am an IT Senior Systems Engineer working from home for the last year or so due to Covid. I have a very highend computer system thus the reason I am using the BR1500MS2. My system draws around 450-500 watts constantly and this UPS supports it just fine. Ok, now on to my point. I live in Colorado and if you remember we recently had a very bad wind storm which knocked out power to most of us in central Colorado for several days. After the second day of no power and no heat (house was 39 degrees). I was pretty much forced to obtain a portal generator. This generator was a highend 8650 Watts from a reputable company. Generator performed as expected - Frig is working, got coffee, have some heat - all good. BTW we were without utility power for 8 days. Wife is happy again, so now it is time to get the computer system and network back on up and running. Here is where you need to be AWARE of using a UPS with Generator Power. I plugged the UPS in to the generator power. Turned on the UPS and after a few seconds, the UPS started to cycle from Gen Power to Battery Power back and forth. That's strange, what could be wrong. Well, it wasn't the input voltage from the Generator - Checked it to be 115v continuous, but UPS still cycling. AH HA, it was the input frequency. The UPS is rated as input frequency to be 60 +/- 3hz. The display on the UPS indicated it was receiving 63hz. So apparently, the Generator was outputting just a hair outside the 60 +/- 3hz range of the UPS specs and causing the UPS to cycle into and out of battery mode. Obviously, it was designed to do this. Ok, unplug all of the stuff from the UPS and plug into generator power and all is good. I need to talk with the generator manufacture on getting the output frequency adjusted no doubt. Sorry for all of the blah, blah, but I wanted to set the expectations if you have an operating environment where you must use a UPS with generator power, you may find yourself in a situation where things may not work as expected due to input/output thresholds of your equipment. Oh, and by the way, the generator manufacture said the Gen was operating within their specs 60hz +/- 3hz. Apparently, the UPS or GEN is not exactly within specs. UPDATE for BR1500MS2: I recently had the need again to use the UPS with my generator. Utility folks replacing power pole, so I powered up the generator to keep a few things running. As I had mentioned previously, I was having an issue with the UPS staying online using the generator voltage. After reading some additional detail about the UPS Sensitivity settings, I adjust the setting from the default of Medium to LOW. The definition of LOW is "Use this setting if your battery backup continues to transfer to battery operation frequently on the medium setting. Typically, this occurs when the AC utility source is a generator. Caution, this will allow greater voltage distortions to reach your computer." Ok, so why couldn't the support folks at APC advise me of this. Maybe because of the caution notice - who knows. Anyway, I set the sensitivity to Low, connected the input of the UPS to the generator output voltage. Ah HA, this time the UPS stayed online and stopped the frequent switching on and off line as before. I monitored the UPS output to my computer and only noticed a small variation in voltage and HZ. Not enough to cause any harm to my system. After utility power was restored, generator off, I put the sensitivity setting back to the default Medium. So I just wanted to update my previous entry about using this UPS with home generators. It does work afterall, just change the UPS sensitivity setting.
