DC-DC converters for railways

5 October 2016 Power Electronics / Power Management

Recom introduced the new RP40-FR DC-DC converter series certified for use in rolling stock as well as industrial applications requiring compliance with recognised safety standards.

EN50155 certification ensures that the RP40-FR series is ideal for harsh environments which can be encountered in railway applications. The new series is also certified according to UL/cUL 60950-1 and is therefore suitable for applications with higher input voltages in industry, telecommunications and distributed power supply architectures.

Along with a wide 4:1 input voltage range, the converters deliver 40 W of regulated output power from single or dual outputs, and come with an output trim function. They also include on/off remote control with positive or negative logic. The series is available with rated DC inputs of 24 V or 48 V with 1,6 kV d.c. insulation or 110 V with 3 kV d.c. insulation. Due to very high efficiency up to 92%, a high power density is possible – 40 W is available in 50,8 x 25,4 x 10,2 mm without a heatsink or 56,8 x 25,4 x 16,8 mm with a heatsink.

The converters in this series are equipped with short circuit, over-voltage, overload and over-temperature protection, and have an extended operating temperature range of -40°C to 105°C. Recom provides a three-year guarantee on the RP40-FR series.
