P-DUKE has introduced the URCD20U series, a line of 20W chassis mount and din-rail type DC/DC converters specifically engineered for railway applications. These converters adhere to EN 50155 standards for electronic equipment on rolling stock and EN 61373 for shock and vibration tests, owing to their robust mechanical design and comprehensive feature set.

The URCD20U series incorporates essential functions including S2/S3 supply interruption solutions, inrush current limitation, reverse polarity protection, EMI filtering compliant with EN 55032 Class B, and an integrated line fuse. These features streamline implementation and reduce development time for end-users.

These converters offer a wide 12:1 input voltage range from 14V to 160Vdc, accommodating various regional power systems with a single module. They provide single and dual outputs of 5, 5.1, 12, 15, 24, ±12, and ±15Vdc. The series includes comprehensive protection mechanisms against over-current, short-circuit, over-voltage, under-voltage lockout, and over-temperature, ensuring optimal system safety and reliability.

The URCD20U series is designed to operate at altitudes up to 5000m and maintains full load operation at temperatures exceeding 70℃. These specifications make the converters particularly suitable for the demanding environmental conditions encountered in railway, rolling stock, and trackside applications.
