Frequency Converter Series FC 400 HZ

The frequency converters of our FC series are intended for the ground servicing of all aircraft types with a frequency of 400 Hz up to 120 kVA. FC series converters assist with the fast, reliable and safe launch of aircraft engines and they provide an uninterrupted power supply when the aircraft is on the ground, reducing the amount of exhaust fumes and noise level within the airport area. FC is intended to supply all types of aircrafts with 400 Hz frequency and 115/200 VAC voltage during preflight preparation and technical maintenance.


Can be manufactured in both standard complete set and also by Client’s special requirements and adjustments.

FC converters 400HZ provide:

  • High-quality three-phase sine output voltage of 400Hz
  • High energy conversion efficiency in all operation modes and low power consumption in idle mode.
  • Significant energy savings
  • High-quality electric power supplied onboard
  • No more than 4% phase output voltage asymmetry
  • Easy control of the maintenance service
  • Cable voltage drop compensation 
  • Possibility to simultaneously service two aircrafts 

400Hz frequency converter is equipped with testing tools for system and component performance testing, advanced monitoring and display system, under and overvoltage protection, as well as output frequency deviation protection.

The converter consists of a single cabinet with a thyristor rectifier, a three-phase inverter, a matching transformer, and a control system

Frequency Converter Series FC 400 HZ are a perfect fit for:

  • Regional airliners including Boieng, Airbus, Antonov An, Tupolev Tu, Bombardier, Embraer, Gulfstream, Cessna, Dassault, Hawker, and others.
  • Our frequency converters are available from 5 to 120 kVA.
