The PPC820 power control unit offers a maximum output current of 1000 A and is compatible with all 12 and 24-volt electric thrusters. The new PPC models now store historical fault codes as well as usage data (such as the amount and direction of thrust on any of the thrusters, remaining operating time, battery status, and temperature). Please note that PJC control panels must be running software version v2.018 or later to support these new units. To upgrade a standard ON/OFF thruster system to PRO (variable speed control), you need a PPC power control unit and an upgrade kit for the internal wiring.
