Synchronous Alternators - G Aircraft

The 400-Hz frequency alternators of the G Aircraft line were developed for application on Ground Power Units (GPU), as power source to supply aircrafts on the ground, driven by diesel engines.

The GPUs are used in cases of maintenance and/or long stays of aircrafts on the ground, replacing the aircraft APU (Auxiliary Power Unit) generator. They reduce fuel and maintenance costs, and the noise generated by the APU.
