3.10 – Regulated 28.5 VDC Ground Power
Connecting DC Power Cable To Unit
Ensure dc power cable plug is fully seated into the MPU's DC Battery Receptacle. Attaching a dc plug is

3.11 – Regulated AC Power
Plugging in with AC Power
When the unit is plugged into ac power, the output is 28.5 volts. This voltage allows the system to recondition
and recharge the aircraft's battery(ies). It is also an optimum voltage for powering avionics and lighting on
most aircraft. The MPU's ac to dc converter produces continuous amps of dc power depending on the size
of the system.
Ensure 120 or 240 Vac power cord is properly connected to an approved ac power supply. After approximately
5-8 seconds, unit's LED status indicator will illuminate indicating power cell state of charge. Cooling fan will
operate. Ensure LED status indicator and cooling fan is operational prior to continuing.
