Behlman Expands Line of 400-Hz Frequency Converters

November 4, 2013. Behlman Electronics Inc. has introduced a new 400-Hz power supply with capabilities beneficial to any markets in which 400-Hz power is used.

115/200-VAC 400-Hz WYE power generation systems are used on most aircraft. There are a great many electrically powered systems aboard aircraft for which an external 400-Hz power source is required for testing, calibrating and repairing. Everything from radars, sensors, weapon systems, cockpit displays, and communications gear to environmental systems, galley equipment, pumps, motors, and entertainment systems operate at 400 Hz.

400 Hz is used on many U.S. Navy ships as well as on land air bases of all the military branches, primarily to service aircraft and avionics. In addition, 400-Hz requirements can be found in spacecraft, submarines, server rooms for computer power, hand-held machine tools, and other industrial applications.

Because frequencies as high as 400 Hz are not supplied by the utilities, a frequency converter is required.

The Behlman FC5003 is an ultra-rugged COTS power supply designed to convert common 120/208-VAC, 3-phase, 60-Hz ground power to 115/200 VAC, 3-phase 400-Hz power used by aircraft and other vehicles and equipment that require 400 Hz.

FC5003 is in a 6U (10.5” high) 19″ rack-mount chassis having an input line cord with a plug and an output receptacle.

Installed in a vehicle or in a wheeled rack or cart, it can readily be moved as needed to service many different aircraft and systems, thereby eliminating the need to use an aircraft’s own 400-Hz generator power. In industrial and manufacturing applications it can be routinely moved close to production lines and test areas to facilitate operations.

According to Behlman president Ron Storm, “In the FC5003 400-Hz power supply we have a unit that can efficiently serve the needs of many industrial manufacturers, service companies, military missions, and commercial aviation.”

A data sheet for the Behlman FC5003 is available at www.behlman.com/modifiedstd.htm#ground.
