Re: [Repeater-Builder] Powering the Repeater With Marine Batteries/ UPS
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. 73,Lee,N3APP Coy Hilton wrote: >For thoes talking about using a UPS. >I have a question.

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries/ UPS
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... back up to full power...

The one I just listed uses an internal DC voltage of 48 volts, with all 4 33AH batteries in series. I agree with you though, the more times you "convert" voltage from one level to another decreases efficiency. At one of our club sites, we have a bank of 6 "2 volt" 500AH cells in series, being charged by a commercial Staticon unit. The batteries only have to last about 2 minutes, as there is a HUGE generator that powers everything at the site.

[Repeater-Builder] Powering the Repeater With Marine Batteries/ UPS
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 transformer to get the 120VAC then turn around and Run it through another transformer to step it down then rectify it to get 13.8 VDC. 73 AC0Y Yahoo!
