Airport rectifiers AV series

AV 28V transformer rectifier unit is used to power the onboard aircraft systems during the pre-flight inspection, as well as to start the engine using the 24/48V system.

AV2 transformer rectifier unit has an option of powering two independent aircrafts at the same time.

AR is intended to supply all types of aircrafts and helicopters with 28,0 /28,5 V.

The rectifiers AV series consists of a single cabinet with a thyristor rectifier, a three-phase inverter, a matching transformer, and a control system.

AV DC transformer rectifier units are a perfect fit for:

  • Helicopters: «MI-8/17», «KA», «Agusta Westaland», «Eurocopter», «McDonnell Douglas», «Sikorsky», «Robinson», «Sweizer», «Bell» and others.
  • Regional airliners including Antonov An, Tupolev Tu, Bombardier, Embraer, Gulfstream, Cessna, Dassault, Hawker, and others.


  • Supply main rated voltage, V 3×400 / 3×380
  • Supply nominal frequency, Hz: 50/60 ± 5%

solid-state technology

Our rectifiers AV series is small and light and easy to tow around in its mobile version. And base on solid-state technology .

The solid-state technology means that wear and tear is limited to a minimum since there are no rotating parts. The result is a very reliable and dependable unit that is built to last for a long time.


The set comes

The converter comes with a standard 10-15 meter cable and a   SHARP-500. Cable length can be extended upon request.
