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.
