Power module for railway applications

12 October 2011 Power Electronics / Power Management

TDK-Lambda has added a 24 V d.c. input series to its CN-A family of railway DC-DC power modules. A robust, quarter-brick 100 W power module, the CN100A24 is compliant with the applicable railway standards and its high-reliability design affords a long warranty period of five years.

Suitable for both rolling stock and fixed installations, the modules enable customers to design cost-effective EN50155 compliant systems without the risks associated with custom product designs, and in a much shorter timescale. Designed for harsh environments, the 100 W module in the CN-A24 series meets the stringent shock and vibration requirements of IEC61373 Category 1 Class B, as well as the Japanese equivalent standard JIS E 4031.

The baseplate-cooled CN100A24 module, with industry standard quarter-brick pinout, accepts a wide input voltage (14,4-36 V d.c.) with 40 V d.c. surge capability for 3 seconds and provides exceptionally high, true useable power from -40°C to +100°C, without derating. With nominal output ranging from 5 to 24 V, it offers up to 88% power conversion efficiency, 3,66 W/cm³ power density and delivers up to 20 A useable output current in a package measuring 36,8 x 12,7 x 57,9 mm.

As standard, all models in the CN-A24 series are equipped with remote sense, remote on/off and input-to-output isolation of 3 kV a.c. for 1 minute, as well as over-voltage and over-current protection circuitry.
