Re: [Repeater-Builder] RS Astron up to 15 volts, will it be ok

Hi Doug, you might be right on the drop, I was taking it from memory as it was nearly 4 months ago that I had them hooked up.  As for as amps, the repeater keyed up draws right about 22 amps according to the meter on the astron.  I have never put another meter inline.  And yes, I want to be able to use the batteries and keep them from killing the power supply if they should ever backfeed.  We lost the repeater the other night when a storm came throught and wipe out the commercial power, was out for nearly 8 hours.

Hi Matthew,
 
The PWRgate 40 is spec'd at 0.4 VDC drop so 13.6 to 12.6 does seem quite high. 
 
How many amps are you pulling through it when you see the 13.6 to 12.6 VDC drop?
 
I have a Samlex supply using Schottky diodes internally and I don't drop near that much.
 
I assume you're using the PWRgate 40 to prevent the batteries from backfeeding and destroying the regulator in the Astron during AC failures.  Is that correct?

Can an Astron RS-70 power supply be taken up to 15 volts and survive ok?  He is the situation.  I have a bank of batteries for the repeater and a West Mountain PWRgate 40 amp switch that goes between the power supply, the batteries and the repeater.  WHen I put it in line, and hook it all up, I loose a considerable amount of repeater power.  Nearly 1/4th of the power.  Measuring the voltage out of the power supply is 13.6 and the voltage out of the PWRgate is about 12.6 volts.Any ideas or suggestions.Mathew Yahoo!
