The best way to get zero switchover time is to buy a UPS that supplies power
from a DC-AC inverter running off of a battery. The battery is then charged
by an AC-DC power supply. This is the way our UPS runs; it has about 10 VAX
minicomputers and 150 workstations hanging off the back. Of course, it has
a room full of batteries too. :-)
I don't know any model names, unfortunately, but you should be able to find
out whether a particular model is set up this way. It's important enough
that it has started to become a sales point.
