INTRODUCTION
The Pump Plus HO Automatic Battery Charger is a compact, completely
automatic, dual channel battery charger designed for vehicles with a two battery
system. The charger is ruggedized to withstand the shock and vibration encountered by vehicle mounted equipment.
Battery Charger Features:
• Independent charge controls for each battery
• Automatic current limiting
• Optional dual battery charge/condition indicator
• Power “ON” LED indicator
DESCRIPTION
Independent Charge Controls
The Pump Plus HO contains two independent charge controls, one for each
battery. This allows each battery to be independently charged while maintaining battery isolation. Each battery is individually sensed, eliminating the need
for sense wires. Each of the charge controls is completely automatic and stops
charging the battery when it is fully charged. There is no trickle charge and
therefore no danger of overcharging and water boil-off.
Automatic Current Limiting
When batteries are severely discharged, some battery chargers can be overloaded due to the high charging current required. The Pump Plus HO contains an
automatic current limit. This circuit limits the output current to the rated 11 amperes when charging a deeply discharged battery or if the starter cranks the engine while starting. The current limiter thus eliminates the need for an ignition
interlock circuit.
