Indeed. Most switchers can actually run perfectly from DC, and ETSI even has a
standard for it - EN 300 132-3. The benefit is that for big UPSes you don't
have to switch into AC again after the battery pack. Less losses.

Cheers,
Magnus - should get a mental examination for actually recalling stuff like that
