INTRODUCTION
The Auto Charge 4000 is a compact, completely automatic, dual channel battery charger
designed for vehicles with a dual battery system. The charger is ruggedized to withstand the
shock and vibration encountered by vehicle mounted equipment.
Charger features:
• Independent charge controls for each battery
• Electronic remote sensing of true battery voltages, eliminates the need
for sensing wires
• Automatic current limiting
• Built-in BATTERY SAVER
• Remote dual battery charge/condition indicator
• Power “ON” LED indicator
• BATTERY SAVER overload indicator
CHARGE CONTROLS & ELECTRONIC REMOTE SENSING
The Auto Charge 4000 contains two independent charge controls, one for each
battery. Automatic electronic remote sensing measures the true voltage of each
battery, eliminating the need for the additional sense wires. The output current of
any charger is inherently a series of pulses whose frequency is determined by the
power line frequency. Therefore there are brief intervals during which no charging
current flows. During this brief interval the Auto Charge 4000 measures and stores
the battery voltage. This voltage is compared to a standard and any error is detected
and used to control the charger output to the desired level. There is no "trickle
charge" and therefore no danger of overcharging and water boil-off.
