Airfield frequency converter 400 Hz

The converter is a static power supply (converter) that converts electrical current from the three-phase mains frequency of 50 Hz to three-phase electric current frequency of 400 Hz.

 

Application:

  • Power supply of planes and helicopters at their pre-flight service to the airport (aerodromes power sources)
  • Power supply voltage of the local objects 400 Hz
  • Power supply test benches for units of aircraft and ships
