Power solution for railway auxiliary systems, 10-40W, high reliability.

The P-DUKE URCD10U, URCD20U, and URED40U series comply with EN50155 and EN61373 standards, achieving stable operation even in harsh environments with robust mechanical design and advanced features. They are equipped with S2/S3 power interruption support, inrush current limiting, reverse polarity protection, EMI filters compliant with EN55032 Class A/B, and built-in line fuses, which shorten system development time. With a wide input voltage range (14V to 160Vdc), they can accommodate railway power systems worldwide with a single module. Options for single output and dual output (3.3, 5, 12, 15, 24, ±5, ±12, ±15Vdc) are available, along with protection features for overcurrent, short circuit, overvoltage, undervoltage, and overtemperature, ensuring safety and reliability. They can operate at altitudes of up to 5000m and maintain full load performance even in high temperatures exceeding 70°C. The URCD10U, URCD20U, and URED40U series are ideal for harsh environments such as railway vehicles, along tracks, and industrial automation. *For more details, please download the materials.*
