GB3/5 - Hybrid 400Hz & 28Vdc Ground Power Unit for civil, military helicopter and business aviation

Specifically designed for starting and maintaining helicopters, the GUINAULT 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 allow 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 28Vdc for helicopter maintenance operations and start-up

As a result of the peak 28Vdc direct current capacity, the GB3/5 GUINAULT GPU is adapted for the majority of helicopters.

The GUINAULT hybrid unit is an autonomous, ultra-compact, light and air portable generator for helicopters, giving, with its diesel-electric hybrid design, very low fuel consumption.

HIGH PERFORMANCES:

• Permanent/peak current
• Voltage/Frequency Transients

RELIABILITY AND ROBUSTNESS:

• KOHLER air cooled engine
• GUINAULT Alternator and electrical regulation
• Full anti-corrosion protection: polyester canopy and electro-galvanized steel chassis for a long term utilization

EASY TO USE:

• Excellent manoeuvrability due to reduced dimensions / weight
• Control panel with clear indication and robust switches
• Possibility to divide it in two modules for easy transportation

REDUCING OF THE TOTAL COST OWNERSHIP:

• Optimized fuel consumption due to the excellent efficiency of the alternator
• Use of air cooled technology for low maintenance cost
• 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 and the Simultaneous Dual-Voltage operation possible for 400Hz and 28Vdc outputs
• Diesel or Jet propulsion fuel (NATO XF-63)
• Possibility to charge helicopter battery + pre-flight checks
