Size and design of equipment is good. Software is easy to install

I had to buy this because a fuse vaporized when the recharging transformer blew open. Shame on APC for being so stingey to return the favor I will be not be buying a part from them but from digikey or futurlec.

I thought that a 550VAR UPS would have been sufficient for my purposes, but the UPS would trip as soon as power was removed from the wall. Some soft start technology would have helped with my problem (running a VERY small water pump).

Attractive (for a UPS); notification; electronically advanced

not enough power output

Seems Good, Needs more space between the 110V AC recepticals

Part arrived well packed and in a timely manner. Unit has functioned as promised and we are well pleased with it.

It seems to be working. It is important to place this UPS far away from Wifi modems as it could cause interference with wifi. It did arrive in time. However, it is not possible for me to say how long the product and battery lasts and how it performs during a power outage.

On occasion, our power goes out for a few seconds and so while only the lights flicker, our computer shuts abruptly down. We purchased this APC battery backup surge protector and have been so happy.

Two weeks ago I purchased this UPS for a computer and one monitor. I also downloaded the PowerChute software from the APC.com website. At first, it said the estimated battery time was 200 minutes. I then ran a couple of tests on the UPS by turning off the power bar it was plugged into.

I bought this to replace a similar product from the same maker that gave some trouble after 8 years of good service. I'm happy with electrical or electronic equipment that lasts beyond 5 years. All APC products that I have exceeded that. I have a larger unit for my multi drive, dual monitor system.

We are a small non-profit, and we need UPS support for our computer systems as we're a medical and dental clinic. These battery back-ups support a computer and two monitors perfectly. They do exactly what we need them to do.
