Combined power unit FCA/AR consists of 400 Hz (5-250 kWt) converter and 28 В (100-1200 А)DC rectifier. Used as aircraft power source in open sea conditions.

Combined frequency converter can be produced in standard set as well as according to special customer requirements.

Designed on standard combined power unit with additional functions which provide more operable convenience in open sea working process:

  • electric charge grounding bolts
  • sealed cable input and connections
  • door locks
  • shock-absorbers

The equipment meets all the standards for extreme working conditions.
