The Kussmaul Auto Charge 1000 PP PLC with Parasitic Load Compensation (PLC) is a compact, microprocessor controlled, completely automatic, single channel battery charger designed for vehicles with a single battery system.

This Parasitic Load Compensation feature is designed especially to meet the heavy duty requirements of emergency vehicles. Most emergency vehicles have many parasitic loads on their systems (flash lights, gas detectors, computers, monitoring systems and other items) that can trick a standard 3 step charger into over charging the batteries. Parasitic load compensation allows you to input the total number of parasitic load amps on the vehicle. Then the charger will shift the absorption stage set point so the battery voltage will drop to the float voltage when the desired current is reached. In short the parasitic loads are invisible to the charger. This will lead to a longer battery life and no overcharging or overheating.

The Battery Saver contained in the Pump Plus 1000 PLC charger is a 3 Amp power supply with a relay to remove the accessory loads from the battery and connect them to the power supply when the charger is energized with A.C. power. This permits the charger to recharge the batteries without supplying the accessory load.

A Dip Switch is provided on the charger to operate an Auto Pump 12V either as a D.C. compressor or as an A.C. compressor. In either switch position the compressor operates from the vehicle's battery. When "D.C." is selected, the compressor operates whenever the pressure switch senses low system pressure. This is useful when parking the vehicle away from the 120 volt input power. For those operators who wish to limit compressor operation to the times when the shoreline is connected to the vehicle, the Dip Switch should be placed in the "A.C." position. This will operate the compressor when the A.C. power is available, but shuts off the compressor when the shoreline is removed.
