Military Compact Mobile Ground Power Unit (GPU) for Military Aircraft & Helicopters - Diesel Engine Driven

Description
Specifications

Especially designed for military application and requirement, the GUINAULT compact GPU GB45 / 20 and GC20 models are the perfect power solution for fighter aircraft, small cargo aircraft and helicopter.

Their incredible ratio performances/size (less than 1,1m height for 45 kVA 115 V / 400 Hz + 28 Vdc power supply) permits to cover a large range of aircraft and to handle it easily and safely on the ramp.

The high efficiency GUINAULT dual voltage alternator enable the use of small compact Deutz oil cooled engine (less than 60KW), best choice for low maintenance cost and low fuel consumption, ie. reduced TCO (total cost of ownership). The 9 phases alternator allows clean power with reduced modulation (18 pulses).

The choice of the GUINAULT product was made, based upon the following criteria:

High performances:

– Permanent/peak current

– Voltage/Frequency Transients

Reliability and robustness:

– Deutz oil cooled engine

– GUINAULT Alternator and electrical regulation

– Stainless steel electrical box with excellent EMC

– 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:

– Low maintenance cost

– Optimized fuel consumption due to the excellent efficiency of the alternator

– Integration of standard components as much as possible

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

Multi-purpose:

– 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: 

– MIL STD 704E, EN 2282, EN12312-20, ISO6858, SAE ARP2015, EC 97/68 & standards.
