Redefining the sources of power

PSDG-48 Series

Fully integrated 48W PSU

Hi-Rel standard compliance made easy

 

The PSDG-48 series is a fully integrated COTS multi-output 48W isolated power supply board mount module. Dedicated to 24 & 28VDC military and High Reliability applications, MIL-STD-461, MIL-STD-704, MIL-STD-1275, ABD100 and DO160 power supply requirements are all built into this unique module :

  • Integrated EMI filter,
  • Reverse polarity protection,
  • Hold-up function (50ms transparency timing managed with external capacitor),
  • High & low input voltage transients and inrush current limit,
  • Short circuit and over-voltage protected outputs,
  • -40°C to +105°C full load case operating temperature range,
  • Ideal for all rugged applications complying with MIL-STD-202 & 810 for altitude, humidity, temperature shocks & cycles, mechanical vibrations and shocks.

The PSDG series use a fixed high frequency switching topology providing a high power density, a low pro-file package and excellent reliability. It is also fully encapsulated with thermally conductive resin for optimal power dissipation in harsh environments.

  • Complete power supply efficiency up to 87%
