New 300W 3U DC-input CompactPCI supply for railway and trackside applications

Gresham Power Electronics has announced availability of a new 3U high, 300W, DC-input, CompactPCI power supply suitable for railway and trackside applications. Designed to meet the requirements of EN50155, the CPCI-3U-DC-300W RL requires a DC input in the range 66-160VDC and has four outputs; +5VDC at 30A, +3.3V at 40A, +12V at 5A and -12V at 0.5A. Maximum total output is 300W with forced air cooling and the power supply is fully protected against output overload, short circuit and over temperature with automatic recovery on removal of overload condition. The operating temperature range of the supply is -40C to +70C at full load with forced air. For system integrators full monitoring command and control is available including remote sense on the two main outputs with maximum voltage compensation for cable losses 200mV. Remote inhibit and enable controls and a power fail signal are fitted as standard. LED indicators show power good and output failure. Current share is available on outputs 1 and 2 and the power supply is designed for hot-swap operation and has an optional I2C interface. The CPCI-3U-DC-300W RL power supply is designed to meet EN50155, is CE marked, meets UL 60950, EN 60950, EN 61000-4-2, EN55022/CISPR22 Class B with an external TBD line filter and is fully compliant to PICMG 2.11 CompactPCI Specification. It has dimensions of 128.7mm x 40.6mm x 162.5mm and weighs 8.50g.
