product image
Part Number :

  • Pulse width-modulated DC to DC converter that provides regulated +28 VDC up to 5.0 amperes
  • Transforms an unregulated input from a 12V battery to a regulated +28 VDC output in a bootstrap mode
  • Primarily intended for use in an aircraft with 12 VDC battery system to operate 28 VDC equipment (especially during periods when the battery is not charged)
  • State of the art design for regulation and positive logic for output overvoltage protection
  • Output is adjustable to 28 ± 2 VDC via an internal trim pot
  • Maximum output voltage is adjustable with an internal trim pot
  • Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202 and MIL-T-5422F class 1A
  • Small and lightweight


Dimensions: 2.3" H x 2. 3" W x 5.8" L Weight: 1.5 lbs.
Input Voltage: 11-16 VDC Input Current: 14-11 ADC
Output Voltage: 28VDC Output Current: 5.0 amps
Efficiency: 87& at full load TSO: C71
Regulation: 2% for line, 2% load and 2% temperature Output Ripple: 50 mVp-p
Altitude: 55,000 ft. Temperature: -55°C to +71°C (sufficient cooling required @ +71°C ambient)
Overload Protection: Output voltage collapses to input DC voltage when load exceeds approx. 6.5 to 7.5 amps Overvoltage Protection: Overvoltage circuit limits output to approx. 33 VDC.
