AFC-7003-(50, -60 or -400)

Behlman's AFC-7003 is a ruggedly built, modified COTS frequency converter designed to convert three-phase aircraft power to regulated single-phase (115 or 230 VAC) 60 Hz ground power.

The AFC-7003 is ruggedly built to support aircraft takeoffs and landings and designed to meet the input power requirements of MIL-STD-704 and RTCA-DO-160.

In the AFC-7003 you'll find the quality features you expect from Behlman. Low output THD, high efficiency, plus excellent line and load regulation.

There's also a unique overload protection system that folds back voltage to maintain rated current without output waveform distortion. Units are supplied with RS-232 remote control and 28 VDC control of Output On/Off. In addition the unit has provisions for slide mounting.

Small size, rugged construction, quiet operation and high efficiency make the AFC-7003 ideal for use on aircraft to convert aircraft power to ground power.


  • Single rack space (6U high)
