PC/104 Power Supply Delivers 60W

The OnPower 60-I intelligent, triple-output PC/104 dc/dc power supply provides up to 60W of output power over a temperature range from -40°C to 85°C without active cooling. Its dc/dc converter module is on the bottom side, allowing it to be heat sunk to a thermally conductive base. The board incorporates a unique mechanical design that withstands extreme temperature, shock, and vibration. Specs include an input voltage range from 18V to 36V, output voltages of 5V at 12A, 12V at 2A, and -5V at 100 mA, a typical efficiency of 88% at full load, input protection, I/O filtering, and reverse protection up to -45 Vdc plus short-term tolerance of spikes up to 50V. Output voltages feed into the PC/104 bus and are accessible from the terminal blocks on the board. Other features include galvanic isolation, configurable timing for power sequencing, and remote shutdown. An optional external filter and input-protection unit are available for MIL-STD-704 compliance. Pricing starts at $429 each/100. PARVUS CORP., Salt Lake City, UT. (801) 483-1533.
