BC Systems AC-DC Converter Serves Military Systems
NY – March 12, 2010 – BC Systems today introduced the BC-751, an 800 W AC-to-DC converter with eight outputs that
is designed to provide power for solid-state RF amplifiers in airborne Identification Friend or Foe (IFF)
The BC-751 accepts a three-phase 155 VAC, 400 Hz input with a power factor of at least 0.88 and maximum
inrush current of less than 13 A, and has overall efficiency of 77%. It provides eight outputs: +3.3 VDC at 45 A
and +5 VDC at 40 A with ripple and noise of less than 100 mVpp, -5 VDC at 600 mA with ripple and noise of less
than 50 mVpp, +51 VDC at 10 A and +24 VDC at 1 A, and +12 VDC at 8 A, -12 VDC at 5 A, and +15 VDC at 3 A with
ripple and noise of less than 120 mVpp.
The converter provides full protection for over-current,
over-voltage, and over-temperature conditions, operates over a temperature range of -40 °C to +85 °C (-55 °C to
+85 °C non-operating), and is designed for use with forced-air cooling. The BC-751 meets CE101 and CE 102
conducted emissions requirements per MIL-STD-461, and shock and vibration to IAW MIL-STD-810D. It measures 8.51 x
8.43 x 3.69 in. and weighs less than 12 lb.
The BC-751 is a custom AC-to-DC converter and many of its specifications as well as mounting and configuration can
be modified by BC Systems to meet customer requirements.
