We needed to replace a very old failing unit but as a non-profit we could not afford a top-of-the-line solution. This unit was cost-effective and is performing superbly. Best of all, the upgrade/exchange program offered by APC is excellent. That, as well as the quality of the products, keeps us coming back.
This is a superb piece of equipment at a good price. It is easy to implement. It is quite heavy and does take up significant space. Supplied wires could be longer to accommodate placement. On a rack or on the floor, distance to power and to equipment matters. I give it top ratings nonetheless. Then again, I am yet to suffer my first lengthy power failure.
This UPS is of the ubiquitous line-interactive topology. At its most basic level it is functional as such. Given its intended use is high power PCs and other such domestic uses, the fan is blessedly silent during normal operation, kicking in only when the inverter is active (during AC fail or buck/boost). Further, the silent mode option does away with annoying alarms during AC fail. I take exception with Energy Star awarding this (and other UPSs) their label: just sitting there, with NOTHING plugged in it consumes over 20 watts, an excessive amount to keep already topped up batteries charged. The LCD panel itself is of nebulous value: the bright back-light cannot be turned off and the information it presents in terms of load/draw is not accurate enough to be of any real use. While not tragically flawed in any way, I do believe one can do better at this price point.
I bought two of these units to power and protect my TV, stereo unit, set top box and DVR whilst the second one powers and protects my security cameras and NVR unit. I am disappointed that the cooling fans are so noisy when the AVR is operating. Our power supply is quiet ordinary with the input voltage always around 130 or even a little higher. Hence tha cooling fan operating most of the time. The unit itself I am happy with with both the protection side and backup power. I had read reviews on other units and this one was suppose to be the quietist when running. If you can put up with the noise then I would recommend buying it.
