The HFC150-W and HEC150-W converters for wall mounting and 19" racks offer an ultra-wide input voltage range from 14.4 V to 154 V with 150 watts of power. One single converter suits for all international on-board power supply voltages for rail vehicles (24 V, 36 V, 72 V and 110 V) including the tolerance range of +/- 40 % required according to EN 50155.
This ultra-wide voltage range is an optimum solution for companies acting Europe-wide offering them the chance to qualify components cost-efficiently with one single converter.
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 with-out additional components. Further, the converter has an integrated hold up time of 10 ms (class S2), which makes the powerful converter really unique. A high efficiency up to 91 % allows the HEC150W to run without any derating within the temperature range of -40 °C to 85 °C according class OT4 ST1.
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 power supplies suits for redundant connection for safety-critical applications. A LED on the front panel indicates the operational readiness.
The chosen PCB material was based on the experience of fire & smoke tests according to EN45545-2.
