Introduction

This articles describes my shack power supplies. The shack operates from AC Mains unless there is a power outage or the 12 VDC Charger is turned off at night. Sometimes, I run beacons through the night and, if the charger is off, I have experienced shutdown of the beacons due to low battery voltage.

Astron RS-20A Power Supply

This supply provides 16 Amps continuous duty with ICS of 20 Amps. Fuse is a GMC 5A. Line draw: idle 215 mA, full load 3.4 Amps

Automatic Shutdown

The RIGRunner has an automatic over or under voltage feature. High Trip is 15 VDC and Low Trip is 11.0 VDC. With both rigs running a beacon at night on battery power only, the battery voltage can drop below 11.0 VDC. This sets of the Low Trip feature and takes the beacons down. 

I had forgotten about this feature so I was initially perplexed to discover the figs had gone off air overnight.

Have pulled the trigger on a logging bench meter. Life is good.
