CompactPCI power supply meets hot-swap railway applications

Designed to meet EN50155, the CPCI-3U-DC-300W RL is a 3U high, 300W, DC input, CompactPCI power supply from Gresham Power Electronics. It is suitable for railway and trackside applications and requires a DC input from 66 to 160V DC. It has four outputs; +5V DC at 30A, +3.3V at 40A, +12V at 5A and -12V at 0.5A.

Maximum output is 300W with forced air cooling. The supply is protected against output over-load, short circuit and over-temperature with automatic recovery on removal of overload condition. Operating temperature range is -40 to +70°C at full load with forced air.

Monitoring command and control is available and includes 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 one and two and the power supply is designed for hot-swap operation and has an optional I²C interface.

In addition to meeting EN50155, the power supply is CE marked, meets UL 60950, EN 60950, EN 61000-4-2, EN55022/CISPR22 Class B with an external TBD line filter and is compliant to PICMG 2.11 CompactPCI Specification. Dimensions are 128.7 x 40.6 x 162.5mm (5.07 x 1.60 x 6.40inch). Weight is 8.50g.
