Tripp-lite?

I have my gear, except for my amps (straight into the wall) plugged into a Tripp-lite Smart700, which has an "automatic switch transformer." I emailed them to find that out. Here is their page on this:

What are your thoughts? I'm just trying to keep a somewhat constant voltage to the equipment.

Thanks!
