Rugged PC/104 DC/DC power supplies for military applications introduced by WinSystems

ARLINGTON, Texas, 3 Feb. 2012. WinSystems Inc. in Arlington, Texas, is introducing two rugged PC/104 wide-input-range DC/DC power supplies for military, transportation, pipeline, communications, and solar power applications.

The input voltage range of the rugged power supplies is 10 to 50 volts DC so they can work with 12-, 24-, or 48-volt battery operated or distributed DC power systems. The standard output voltage for the PCM-DC-AT500 power electronics module is 5 volts at 20 amps. For the triple-output PCM-DC-AT512, the voltages are 5 volts at 20 amps, 12 volts at 3 amps, and -12 volts at 0.5 amps. Both versions will operate in temperatures from -40 to 85 degrees Celsius with no fans or heat sinks.

The PCM-DC-AT power supplies have no minimum load requirement to bring the units into regulation. All the outputs have overvoltage and short circuit protection plus overcurrent protection as well. The PCM-DC-AT has individual LED indicators which display a visual status of each regulated output.

Power comes from a standard two-pin plug and connector system. The output voltage is wired to the PC/104 connector. The PCM-DC-AT512 also has two four-pin connectors at the edge of the board to provide 5 volts and 12 volts to disk drives and other accessories. The two power supplies are RoHS-compliant, and measure 3.6 by 3.8 inches.
