That page is specific to the BackUPS product. And that is why I always
buy SmartUPS online UPSs instead. Although, I notice they point out
that only SmartUPS over 700va output a pure sine wave. I've never
bought a smaller one, but that would be good to remember.
I could be wrong, but I figure that a SmartUPS online UPS is a pretty
good power filter for AV equipment as well.
