Mean Well RSD-30L-24 30W 24V 1.25A Isolated Railway DC/DC Converter

The Mean Well RSD-30L-24 is a high-reliability, 30W enclosed DC/DC power converter designed specifically for demanding railway and harsh-environment applications. Engineered to meet rigorous industry standards including BS EN/EN50155 and IEC60571, this robust unit ensures dependable operation in critical systems. It features a 4:1 wide input voltage range, making it suitable for various on-board power configurations found in trains, trams, metro systems, and buses.

Constructed with an ultra-compact, low-profile enclosure measuring just 25mm in height, the converter is built to withstand severe conditions. Its interior is semi-potted with silicone, offering excellent resistance to high vibration, dust, and extreme temperatures from -40°C to +55°C. This design ensures stable performance for in-car electronics, trackside facilities, and other installations exposed to challenging environments.

The converter delivers a clean and stable 24V DC output at 1.25A, with a typical efficiency of 84%. It boasts superior electromagnetic compatibility (EMC) characteristics and features low ripple and noise. Comprehensive protection is provided through built-in short circuit, overload, and over-voltage safeguards, alongside a constant current limiting circuit. An LED indicator provides clear visual confirmation of power-on status, and cooling is efficiently managed via free air convection.
