Our 270 VDC / 400 Hz Dual Output Converter is the only power supply of its type in the industry. The 270 VDC meets the tough requirements for today’s most advanced fighter aircraft (F-35 and F-22). In addition, the 400 Hz meets or exceeds MIL-STD-704 with the added advantage of individual phase control. This unique dual output converter is compact, light weight, quiet, and extremely small. It can be floor or overhead mounted, and is also available on a small trailer for ease of mobility.
