KUSSMAUL AUTO CHARGE LPC Series Instruction Manual page 3

INTRODUCTION
The AUTO CHARGE LPC SERIES is a low profile, completely automatic, single channel,
battery float charger designed for vehicles with a single battery system. The LPC improves
upon package size and parasitic systems. The charger is also ruggedized to withstand
the shock and vibration encountered by vehicle mounted equipment.
FEATURES
• Charger controller
• Automatic current limiting
• Remote voltage sense
• Remote charger indicator display
• LED status indicators
• AUX output with AC or DC mode rocker switch and automatic fuse protection
• AC input circuit breaker protection
• Fan cooled
• Reverse polarity protected by external inline fuse
FUNCTIONALITY
Charger Controller:
The Auto Charge LPC contains a precision voltage controller to regulate the output voltage.
Using high-frequency switching technology the output terminal voltage is compared to
a reference voltage, any error detected is then used to control the charger output at the
desired level. 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 Auto Charge LPC contains an automatic current
limit circuit. The current limit feature limits the output current to 80 amperes when charging
a deeply discharged battery, or if the starter cranks the engine while charging. The current
limiter thus eliminates the need for an ignition interlock circuit.
Remote Battery Sense:
Adding sense leads from the charger to the battery compensates for voltage drop in the
charging wires. The charger automatically compensates for this voltage drop and boosts
the charger output voltage in order to maintain the voltage at the battery constant.
