GUINAULT-LEBRUN GPU
The Standard
Specifically designed for starting and maintaining
helicopters, the GUINAULT-LEBRUN HYBRID
generator is a powerhouse at very low cost: the
charged batteries add their capacity to the diesel
motor-generator in order to ensure the peak
currents necessary for aircraft start-up. The dual
voltage alternator allows it to simultaneously
provide:
• an alternating current (AC) of 115 VAC/400 Hz
required by the on-board electronics during
flight preparation
• a direct voltage of 28 VDC for helicopter
maintenance operations and start-up

As a result of the peak 28 VDC direct current
capacity, the GB3/5 & GB3/2 GUINAULT-LEBRUN
GPUs are adapted for the majority of helicopters.
The GUINAULT-LEBRUN hybrid unit is an
autonomous, ultra-compact, light, and air portable
generator for helicopters, giving, with its dieselelectric hybrid design, very low fuel consumption.
