19inch, 6U switched-mode power supply for high-power CompactPCI

As well as incorporating a P47 connector conforming to the PICMG 2.11 CompactPCI specification, the PSU also provides the high levels of reliability demanded by typical CompactPCI applications in the industrial, communications, military and aerospace sectors.

Inputs are protected against voltage transients and high inrush currents, outputs are protected against open-circuit and short-circuit conditions, and the power supply also includes over-temperature protection.

The unit can be hot-swapped, and active current sharing is provided on three of the outputs for parallel operation of multiple units in n+1 redundant designs or in systems requiring a higher output power.

Measuring 6U high x 8HP wide x 172mm deep, the new PSU is supplied with an EMC seal and a 19inch front panel including handles. It achieves a typical efficiency of 84 per cent and meets the requirements of the relevant standards covering safety, EMC and mechanical stress.
