For thoes talking about using a UPS.
I have a question. ARE you powering the AC side of your repeaters
from the UPS? If so what about the input current rating of the power
supplies and the fact that it is terrably in-efficient to take
13.8VDC input run it through an inverter,a step up

Any UPS that is big enough to handle the load of a
repeater is usually powered by 24 volts or more
(many 12 volt batteries in series).
The one I just listed uses an internal DC voltage
of 48 volts,
My machines all run 12 volts when I loose 120Vac the only thing I
loose is the power amp so the machine goes from 180 watts down to 30
watts the UPS backup is for the Computer in the shack. when that dies
Ohh well no big loss the backup Generator should be running
before that happens...
I only use it to run the computers,main repeaters are full time DC
powered direct from the battery banks.
Computers for EchoLink,IRLP,server and two TCX-150 repeater controllers.
