Martek Power offers compact PCI power supply for on-board rail use

Martek Power—manufacturer of power subsystems for rail and other demanding applications—has launched its Powertron CPCIR series of DC-DC converters. Providing 100 W (max), the CPCIR series meets the exacting requirements of EN50155 for on-board computer applications.   As standard, the triple output CPCIR power supplies operate from 72/110 and 24/36 VDC inputs and provide 3.3, 5.1, and 12 V outputs. Conforming to the standard cPCI profile, these are convection-cooled units that will operate between -40 to +70 °C and up to +85 °C for 10 minutes without derating (EN50155 Temperature Class TX).   Key features include high efficiency, a hold up time of 10 ms from nominal voltage, input and output protection, thermal protection, and input and output status indication. With a height of 3U, the CPCIR series features a conformal-coated PCB and includes an EMC screened front panel and lower ejector as standard. An optional ventilated enclosure offering protection to IP20 is also available.   In addition to meeting EN50155, the units comply with EN50121-3-2 (2006), EN55022 Class B and EN61000-6-2 for EMC, EN60950 for safety and NF-F-16-102 category A2 for fire and smoke.
