Power Supply Units Suit CompactPCI Applications

Schroff UK has expanded its 19in Maxpowerpro range of switched-mode power supplies with the addition of the 13100-145 - a 6U model designed for high-power CompactPCI applications. The 13100-145 power supply features an output voltage of 500W and operates from a wide input voltage of 90-264V AC with PFC. It delivers output voltages of 5V, 3.3V, 12V, and -12V.

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 communications, industrial, 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 is hot-swappable 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 PSU is supplied with an EMC seal and a 19in front panel including handles. Schroff said the power supply achieves a typical efficiency of 84 per cent and meets the requirements of the relevant standards covering safety, EMC and mechanical stress.
