Mobile 400 Hz Ground Power Unit (GPU) (Diesel Engine Driven) from 90 to 180 kVA


The GUINAULT Ground Power Unit ensures the supply of electrical power to both civil and military aircraft, of all types in the most extreme

environments. Their ultra-sturdy design is fully protected against corrosion and is engineered to withstand harsh conditions in airport

environments. The modular design enables the integration of numerous options within a universal standard. The logical commonality of

elements assists in the functional understanding of the machine, and contributes to the quality of maintenance.

High performances:

– Permanent current

– Peak current

– Voltage Transients

– Frequency Transients

Reliability and robustness:

– Deutz, Cummins or Ford engines

– GUINAULT Alternator and electrical regulation

– Full anti-corrosion protection: polyester canopy, plastic fuel tank and electro-galvanized steel chassis for long term utilization

Easy to Use:

– Excellent manoeuvrability due to reduced dimensions / weight and the leading front axle with ball bearing for low turning radius (= wheel base)

– Control panel with clear indication and robust switches

– Easy access for maintenance: Possibility to uncover entirely the device by swinging the canopy and opening the rear panel

Reducing of the Total Cost Ownership:

– Optimized fuel consumption due to the excellent efficiency of the alternator, the automatic stop after 20min if no load is provided, the low speed alternator 1714rpm option to save up to 15% fuel consumption and anti-towing security option to save fuel during no load time

– Low cost of spare parts due to the choice of standard components as much as possible


– The GPU guarantees an adapted power supply for numerous types of aircrafts thanks to the high temporary overloads tolerated by the alternator and the Simultaneous Dual-Voltage operation possible for 400Hz and 28Vdc OUTPUTS

Complies with applicable standards in force: 

– EN2282 / ISO6858 / EN12312-20 / SAE ARP 5015A / EN1915…

– Directives 2006/42/CE and 2004/108/CE and delivered with CE Certificate.
