Are the UPS's that have a sine wave output also called "line
conditioners"?

The computer power supplies work fine with the 115 VAC (RMS) square wave
output from the low cost UPSs. Most consumer electronic equipment is
rated
for 115 volt RMS 60 Hertz sine wave, plus or minus 10%. If you use the
computer UPS with consumer electronic equipment the internal voltages
and
losses are different than the spec., so you are not sure if you will
have
functional problems or if things will overheat. A lot of stuff will
probably
work OK, but you cant be sure. So the suggestion was made to use UPSs
that
have a sine wave output and these are many times more expensive than the
ones with a square wave output.
