DASSAULT AVIATION Proprietary Data
GPU
An approved 28 VDC Ground Power Unit (GPU) may be used for prolonged periods to
power the DC system in order to facilitate maintenance and servicing.
The GPU may also be used:
-
For APU starting (recommended power is 1,000 A),
-
To charge the batteries.
The GPU will not provide power to the distribution system simultaneously with APU
generator or engine-driven generators. Order of priority is the following:
-
The APU generator will provide power to the distribution system only once the GPU is
off line,
-
The GPU is automatically disconnected from electrical buses when one engine-driven
generator comes on line.
