Switched-mode PSU for high-power CompactPCI applications

Paul Boughton
Schroff's new maxpowerPRO 13100-145 power supply is a 19inch, 6U switched-mode model for high-power CompactPCI applications. With an output of 500W, it operates from a wide input voltage range of 90-264V AC with PFC and delivers output voltages of 5, 3.3, 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 required for 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. The power supply also benefits from over-temperature protection.
The PSU 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 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.
