Railway & Transit Ruggedized DC/DC Converters

TRACO Power Railway and Transit DC/DC Converters are qualified to EN 50155 and EN 61373 standards as well as UL 60950-1 approved. These converters are additionally certified to IEC/EN/UL 60950-1, and several product families in the TEQ series also carry UL 508 certification for demanding Industrial requirements. The product offering covers 3W to 300W, with PCB-mount units from 3W to 240W and chassis-mount types covering 20W to 300W. These converters offer continuous operational input ranges that exceed the defined input voltage ranges of EN 50155. The DC/DC converters have galvanic isolation up to 2250VDC (input-to-output or input-to-the-case).
