INTRODUCTION
The Auto Charge Dual 12 volt-20 amp. Battery Charger is a compact, completely automatic
charger designed specifically for installations that require 24 volts for starting and 12 volts
for accessories. The two batteries are connected in series to obtain 24 volts and the output
of each charger is connected to each battery. Each output of the charger is individually
controlled to charge it's particular battery and is electrically isolated from the other. Two
separate ammeters indicate the output current to each battery.
Construction of the Auto Charge Dual 12 volt-20 amp Battery Charger is extremely rugged
to withstand the shock and vibration encountered in vehicle mounted equipment. Each
output operates completely automatically and stops charging its battery when the battery is
fully charged. There is no trickle charge, and therefore no danger of overcharging and water
boil-off. Any parasitic loads on the batteries such as radios, lights, etc., are automatically
supplied by the respective charger output.
