PULS Power provides reliable, efficient and robust DIN-Rail power supplies for railway applications. Ideal for both trackside and on-board train equipment the railway range of power supplies provides 100% greater mains failure bridging time than needed by the railway standard EN 50155 (S2), are weather-resistant with all PCBs having conformal coating as standard and are completely convection cooled further increasing reliability and minimising system noise.

All models have a nominal 110VDC input with a wide voltage fluctuation tolerance of -30% to +40% and are available with an output voltage range from 24VDC to 28VDC with power ratings of 100W, 200W and 400W. Depending on model operating temperature range is from -40C to +70C with no derating and typical efficiency is greater than 94%.

Fully EN 50155 certified the PULS DIN-Rail power supplies are classified according to T3, TX, C2 and S2 for use on rolling stock. They also meet EN 61373 for shock and vibration, EN 50121-3-2 for EMC requirements and EN 45545-2 for fire protection on a railway vehicle according to hazard level HL3.

Marco van der Linden, UK country manager, for PULS comments, “The advanced, robust, reliable and efficient design of our DIN-Rail power supplies makes them ideal for railway applications. They offer many advantages over chassis mounted types including ease of installation, the ability to upgrade in the event of a system change and simplicity of installation and maintenance.”
