You also need to look at how a UPS provides AC power to the devices plugged 
in to it. The method used determines various operational factors such as 
time to switch between hydro and backup power, and the ability to handle 
brownouts, over voltage conditions, and power spikes and noise on the hydro 
AC line.

There is some good information about different types of UPS in Wikipedia at
