APU Power Supply

The D B Assembly, Inc. P-28100 is designed to operate avionics equipment for commercial aircraft servicing.

This equipment will provide the amps needed for gear retraction tests as well as the filtered power for all types of avionics service.

The P-28100 will furnish up to 100 amps at 28 VDC. It plugs into the APU connector on the engine cowling and automatically disconnects the battery so that it will not be drained by the servicing processes.
