But you did not say anything on the duration of each confgn (give the lowest back-up time for each). and the number of batteries required and the supply input voltage range. Considering the fact that in many occasions we have low voltages (as low as 150V or less!!). In this case will these UPSes supply from the battery of it will try to stabilize the low voltage?

Nice
