My old BackUPS LS 500 is silent. When it is not running on battery, there is no hum or slight buzz at all -- nothing. I like that.
I just got a BackUPS CS 350, hoping it would be silent too, but it has a slight hum/buzz to it. When the room is very quite, you can hear it from 10 feet away.
Does anyone know of a good brand of UPS that is silent, and around 300-500VA?
