Fri, 04/16/2010 - 8:26am
800-W AC-to-DC converterBC Systems introduced the BC-751, an 800 W AC/DC converter with eight outputs to provide power for solid-state RF amplifiers in airborne Identification Friend or Foe (IFF) applications. The converter accepts a three-phase 155 VAC, 400 Hz input with a power factor of at least 0.88 and maximum inrush current of <13 A, and has overall efficiency of 77 percent. 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 -40o C to +85o C (-55o C to +85o 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.
