Behlman's
AFC-7000 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-7000 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-7000 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-7000 ideal for use on aircraft to convert aircraft
power to ground power.
