MEAN WELL RSD-30G-5 DC/DC Converter, 5V DC 6A, 30W, Railway Grade

The MEAN WELL RSD-30G-5 is a robust, enclosed 30W DC/DC converter engineered for reliability in demanding railway and transportation applications. Designed in compliance with the stringent BS EN/EN50155 and IEC60571 railway standards, this converter delivers stable and clean power essential for critical in-vehicle systems.

Featuring a 4:1 wide input voltage range (9–36VDC), it offers exceptional flexibility for various power sources. Its design prioritises low ripple and noise, coupled with superior EMC characteristics, ensuring compatibility with sensitive electronic equipment. The unit provides 4kVDC isolation between input and output, enhancing safety and system integrity. Its ultra-compact, low-profile enclosure (25mm height) and semi-potted silicone interior provide robust protection against harsh environmental conditions, including high vibration, dust, and extreme temperatures from -40°C to +55°C.

Comprehensive protection features include short circuit, overload, and overvoltage protection, alongside a built-in constant current limiting circuit. An LED power indicator offers convenient status monitoring. With a typical efficiency of 84% and no minimum load requirement, it operates efficiently via free air convection cooling.

This reliable power supply is approved to IEC 62368-1, UL 62368-1, AS/NZS 62368-1, and EAC TP TC 004 standards, making it suitable for a global market. Its half-encapsulated construction ensures durability and long-term performance, ideal for integration into railway carriages, trams, buses, and metro systems, as well as telecom, datacom, and wireless network infrastructure.
