Guinault GA100V, Ground power unit

Length 7750
Width 3050
Height 3650
Weight 5800

Ground power unit produces 400Hz and 28VDC power
to supply the aircraft during a stop on the ground.
The unit can be operated for maintenance and handling purposes.

The engine, driving the alternator,
settles the frequency of the alternative generation.
The electronic speed regulation ensures the stability
of the performances in continuous working and during transiants,as per GPU performances and ain compliance
with the standards in force.

When the alternator is driven by the engine at its nominal power,
the alternator supplies the power required by the aircraft,
up to the dimensioning nominal power and admissible overloads.
The voltage regulator ensures the stability
of the performances in continuous working and during
the load transients, in compliance with the standards in force.
