Amirm, thanks for pointing that out about the wave only applying during battery use, when not using the mains.
I don't want to run my HT off of a battery. My primary concern is a power conditioner: to protect my equipment from brownouts, etc.
So yes, I will be using mains almost entirely.
I don't listen to loud music, and the sub amp will not be plugged into this. I won't exceed the power rating.
I want to plug a Plasma TV, Receiver, Cable DVR, and Consoles into it.
Are any of those likely to be damaged by type of wave this UPS uses, when it switches to battery for a very short period during loss of power?
