Power Supplies for Railway
High-Performance DC/DC Converter HFC200-W of Autronic - 200 Watt for railway & more
The DC/DC converter HFC200-W/O for wall mounting has an ultra-wide input voltage range between 14,4 and 154VDC with a power of 200 Watt. So one single converter suits for all international on-board power supply voltages for rail vehicles (24V to 110V) including the tolerance range of +/- 40% required according to EN 50155. This ultra-wide voltage range is an optimum solution for companies offering one product as European solution.
With regard to temperature, shock, vibration and the railway-specific EMC criteria according to EN50121-3-2, as well as radiated emissions, surge, burst and ESD strict compliance with EN50155 is provided without additional components. Further, the converter has an integrated hold up time of 10ms (class S2). Two small gap filler at the bottom of the PCB acould be used for heat transfer to the case. A high efficiency allows the HFC200 to run without any derating within the temperature range of -40...85°C according class TX.
Standard features are inrush current limitation as well as excess voltage and excess temperature protection, in addition, the converter is open-circuit stable and continuously short-circuit proof.
The chosen PCB material was based on the experience of Fire & Smoke tests according to EN45545-2.
