2025 Air Business Corporation ABC400-5000SB-55-26

ABC400-5000SB-55-26 Combination Unit is a state-of-the-art design model that supplies true 28.5VDC output, with no input mains applied. The unit has a dual purpose: it provides 28.5VDC continuous power for avionics work and also used to start the aircraft or APU.

The unit can operate in either AC Mode (power supply modules get power from the 3-phase input mains applied) or DC Mode (power supply modules get power from the internal batteries), all batteries automatically charge when connected to input power.

This unit is very quiet and simple to operate. The unit is fitted on the trolley with 6 rubber mounts to absorb any vibration.
