75 or 150 Watt DC/DC Converter, 3U cPCI, Holdup

NAI's 75PS4 is a rugged, high-performance 75W or 150W DC/DC power supply designed for the aerospace, defense, and industrial markets. This programmable, switching COTS conduction-cooled converter accepts a +28 VDC input and plugs directly into a standard 3U cPCI chassis with a 0.8” slot. The 75PS4 uses NAVMAT component derating and offers an optional reverse polarity protection and holdup time. Its dual microprocessor-controlled design and innovative architecture provides an exceptionally robust solution to the difficult problem of supplying clean power to upstream electronics, while operating in extreme conditions.

  • Optional holdup time (50 ms for 150 W version, 100ms for 75 W version)
  • Wide input range - +28 VDC nominal (+15 to +50 VDC continuous)
  • Extremely low quiescent power (5 W for 150 W version, 4 W for 75 W version)
  • Input transient protection per MIL-STD-704A through F and optional reverse polarity protection per MIL-STD-1275AT
  • Operates at full load through the entire -40° C to +85° C temperature range
  • User programming interface using supplied GUI via USB port on front
  • Standard cPCI 47-pin connectors per PICMG 2.11
  • Integrated EMI filtering per MIL-STD-461F
  • IEEE 1101.2 compliant
  • Efficiency - up to 90%
  • I2C communication
