The Kussmaul Electronics Auto Charge 2000 PLC, which replaces the original AC2000, a dual-battery bank charger with PLC (Parasitic Load Compensation) technology, is fully customizable to the needs of each truck which solves a common problem with parasitic loads. This charger utilizes a three-step charging algorithm with the ability to shift the absorption stage and put the charger into float mode, which is done by the user inputting the parasitic load draw into the charger, so once the desired battery current is reached, the charger will switch over to float mode. The Auto Charge 2000 PLC also has a 3 amp battery saver on a separate circuit that can be turned on or off which allows a small load to be charged separately.
