3U VPX 400W 28V DC power supply

The Isolated Rugged 3U Dual Phase Power Supply works with 14 to 36 VDC (28VDC nominal) input voltage and isolates the input voltage ground from the output voltage ground.
The Isolated Rugged 3U Dual Phase Power Supply is conduction cooled, uses dual phase technology on all voltage rails and can provide up to 400 watts.

  • up to 400 watts, 450 watts peak
  • 14-36VDC (28VDC nominal) power input.
  • 1500V isolation between input / output.
  • Output voltages of +/-12V, +5V and +3.3V as well as 3.3V aux are standard.
  • Vita 46 and 48 Ready


  • Over Temperature Protection (OTP):     85°C
  • Over Current Protection (OCP):            Installed at each rail
  • Over Load Protection (OLP):                 Typical 120% max. load, fully protected against output overload or short circuit.
  • Over Voltage Protection (OVP):             Built-in at all outputs


This board is available with Amphenol Backplane Systems VITA 46 / 48 compliant VIPER™ VPX connectors. This is an extremely ruggedized 10Gbps connector, securing tomorrow’s most intensive land based, marine and avionics environmental packaging challenges.
