RSD-30H-24 30W Railway Certified Dc-dc Converter

Robust, Reliable Power for Demanding Railway & Industrial Applications Engineered for resilience, the Mean Well RSD-30H-24 is a high-performance 30W enclosed DC-DC converter designed to excel in the harshest environments. It is fully compliant with railway standards BS EN/EN50155 and BS EN/EN45545-2, making it the ideal power solution for rolling stock, railway systems, trams, buses, and other demanding transportation applications.

Its rugged design also suits industrial systems that experience high vibration, dust, and extreme temperatures. Engineered for Performance and Safety The RSD-30H-24 features a 4:1 wide input voltage range of 40-160VDC, accommodating common railway power systems like 72V, 96V, and 110V. It delivers a stable, regulated 24VDC output at 1.25A.

With 4000VDC I/O isolation, this converter ensures system safety and signal integrity. Comprehensive protections, including short circuit, overload, over voltage, and input reverse polarity, are built-in to guarantee operational reliability and longevity. Cooling is achieved through free air convection, allowing it to operate in temperatures from -40C to +70C.
