With special mechanical designParvus Corp. disclosed that it will soon release its new 60W, triple-output galvanically isolated PC/104 Bus dc-dc power supply that features a special mechanical design hardened for extreme temperature, shock and vibration.

Designed to meet the demanding requirements of aircraft, ship and industrial installations, the OnPower 60-I board includes an onboard microcontroller dedicated to monitoring ambient temperatures and protecting the system from excessive thermal stress. It incorporates a dc-dc converter module placed on its bottom side so that it can be structurally heatsinked to a thermally conductive base. This will enable reliable extended temperature operation (-40C to 85C) without any active cooling (fanless), said Parvus.

Input protected and filtered, the OnPower 60-I is suitable for battery-operated 24Vdc nominal systems. It offers reverse protection up to -45Vdc and short-term tolerance of spikes up to 50V (1ms). An optional external filter and input protection unit can be supplied if compliance with MIL-STD-704 is required.

Output voltages are fed into the PC/104 bus and can also be accessed from the terminal blocks on the board. It also supports configurable timing for power sequencing, as well as remote shutdown. Indicator LEDs display the status of each power output. Voltage input range is from 18Vdc to 36Vdc.

The OnPower 60-I is expected to be in stock by early Q3 2005. Pricing starts at $429 each in volume orders of 100+ units.
