DC/DC Power Supply


WinSystems today announced two new PC/104 wide input range, DC/DC power supplies.  The input voltage range for the units is from 10 to 50V DC which allows them to work with 12, 24, or 48 volt battery operated or distributed DC power systems.  The standard output voltage for the PCM-DC-AT500 is +5V @ 20A.   For the triple output PCM-DC-AT512, the voltages are +5V@20A, +12V @ 3A, and -12V @ 0.5A. 

Both versions will operate from -40° to +85°C with no fans or heat sinks and are well suited for applications including pipelines, transportation, communications, solar power, and military. 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 is input through a standard 2-pin plug and connector system for easy connection and removal.  

The output voltage is wired directly to the PC/104 connector.  On the PCM-DC-AT512 there are also two, four-pin connectors at the edge of the board to provide +5V and +12V to disk drives and other accessories.  Both the PCM-DC-AT500 and PCM-DC-AT512 are PC/104 and RoHS-compliant.  They measure 3.6” x 3.8” (90mm x 96mm).
