The PD2180 is a 80-amp Electronic Marine Converter/Charger capable of charging up to three separate banks of batteries at the same time. It incorporates a microprocessor that constantly monitors battery voltage, then automatically selects one of four operating modes to ensure safe, rapid recharging cycles. The Storage Mode and the Equalize Mode of operation ensures minimum battery gassing and water loss while preventing battery stratification and sulfation. All Inteli-Power chargers are designed to meet the stringent requirements of the Marine environment and are UL listed for safety. A digital meter displays current, voltage, operation mode, blown fuse indication, and battery type. Four-Stage Charging System- patented Microprocessor constantly monitors battery voltage and automatically selects one of the four charging modes; BOOST, NORMAL, STORAGE or EQUALIZE. 3 Diode Isolated Outputs- allows the converter/charger to charge three separate banks of batteries. Each output is capable of handling the full rated current of the charger. Patented Reverse Battery Protection- prevents converter/charger from being damaged if the batteries are accidentally connected to the charger in reverse. Over Voltage Protection- prevents high voltage spikes from damaging the converter/charger. This product ships in approximately 1 days
