I've had two or three APC UPS units burn up, in the sense of emitting
smoke; that is a bit scary. Cleaning house a week ago, I came across
six or seven APC units of various models which have failed within the
past five years; these all went into the dumpster. I now refuse to
purchase APC; APC appears to spend more on advertising than on
I currently am well pleased with Powerware units, which are used in
the broadcast industry. Powerware advertises advanced battery
management circuitry which is said to increase battery life by a
substantial factor. Also, even the lower-cost Powerware units provide
a nearly-sinusoidal waveform, rather than a stepped wave. (The more
expensive Powerware units provide a pure sinusoid.) Powerware may be
purchased in the US through BSW (www.bswusa.com).
Another respectable UPS manufacturer is Tripp-Lite.
