100W, Encapsulated AC/DC Power Supply suits Extreme Environments

Full encapsulation in a thermally conductive MIL-grade silicon rubber compound ensures resistance to high levels of shock, vibration and moisture. The unit operates in a -40°C to +70°C cold-plate temperature range for full specification without derating. Cooling is via base plate to the customer’s heatsink or chassis. The PWI 100 measures 81 x 66 x 156 mm and weighs 0.95 kg.

The PWI 100 is suitable for operation in extreme environments including industrial automation, transportation, oil & gas and mining. A railway version that complies with EN 50155 for electronic equipment used on railway rolling stock is also available.

This rugged power supply meets IEC 61371 Categories 1 A and B shock-and-vibration standards as a minimum, and has input and output filtering in compliance with EN55022 EMI standards. It also complies with the requirements of EN60950 and related standards. The unit features full electronic protection on the input and output, which eliminates the possibility of failure due to abnormal operating conditions, including application errors. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF.
