10-40W Reliable DC/DC Solutions for Railway Auxiliary Systems

P-DUKE Technology introduces the URCD10U, URCD20U, and URED40U series—chassis mount and DIN-rail DC/DC converters designed for railway auxiliary systems. These converters comply with EN 50155 standards for rolling stock electronics and EN 61373 for shock and vibration resistance, ensuring robust operation in harsh environments.

Key features include S2/S3 supply interruption solutions, inrush current limitation, reverse polarity protection, EMI filtering compliant with EN 55032 Class A/B, and an integrated line fuse, simplifying system integration and reducing development time. The 12:1 wide input voltage range (14V to 160Vdc) enables adaptation to diverse railway power systems worldwide with a single module. Single and dual output options (3.3, 5, 12, 15, 24, ±5, ±12, ±15Vdc) are available. Comprehensive protection features—over-current, short-circuit, over-voltage, under-voltage lockout, and over-temperature—ensure maximum system safety and reliability.

These converters operate at altitudes up to 5000m and maintain full load performance above 70℃, making the URCD10U, URCD20U, and URED40U series ideal for railway, rolling stock, and trackside applications.
