The Kussmaul Electronics Auto Charge 2000 PLC is a compact, microprocessor controlled, automatic, dual channel battery charger designed for vehicles with a dual battery system.

The PLC charger is designed to withstand the shock and vibration encountered by vehicle mounted equipment. The new parasitic load compensation feature is designed to meet vehicles with heavy electronic loads such as vehicles equipped with flash lights, gas detectors, computers, monitoring systems and other similar items.

Parasitic loads can trick a standard 3-step charger into overcharging batteries but the parasitic load compensation allows a user to input the total number of parasitic load amps on the vehicle.

The charger will then shift the absorption stage set point so the battery voltage will drop to the float voltage when the desired current is reached. This makes parasitic loads effectively invisible to the charger, according to Kussmaul, which can lead to longer battery life and prevents overcharging and overheating.
