Diesel engine driven Ground Power Unit series APA

Diesel engine driven GPU series APA is designed to supply electrical equipment onboard aircraft and helicopters with constant voltage 28,5V (up to two output channels) and three-phase alternating 3x115V frequency 400Hz (up to three output channels). These GPUs have diesel generator sets, providing a three-phase AC input voltage 3x400V for rectifiers EAR and frequency converters EAC. The diesel generator unit and unit conversion equipment mounted on a single frame, which, in turn, is mounted on a truck chassis.

An additional 3-rd output with 400Hz 36V of power up to 10kW can be designed in a power supply unit. An energy intermediate unit ensures a smooth load variation to the diesel-generator. It means, that you get high stability of output voltage and fixed frequency 400Hz+-0,01% at any unstable load level.

There is an additional output of standard voltage 50/60Hz. The customer can perform the complete service of aircrafts at remote parking plots with the possibility to supply power of common loads with standard voltage 50/60Hz without having to buy additional equipment. This saves time and simplifies service processes at remote parking places.
