Mobile Ground Power Unit
Product Overview:
Mobile Ground Power Unit (GPU) is a portable aviation ground power supply for aircraft.
It converts commercial mains power into standard 400Hz aircraft power, delivering stable pure sine-wave AC power for aircraft when the onboard engine is shut down.
It adopts modular IGBT/SPWM power conversion architecture, features compact movable design, low noise, fast dynamic response and comprehensive protection.
Typical Applications:
1、Civil & military aircraft ground power supply at airport apron
2、Aircraft manufacturing, assembly and factory power-on test
3、Aircraft routine maintenance, overhaul and fault inspection
4、Airborne radar, navigation and avionics equipment ground test
5、Field airport, temporary air station mobile power support
