Product Description
MEAN WELL RSD-200C-48 is a 200W railway certified regulated isolated DC-DC converter designed for industrial and transportation applications requiring stable and isolated power supply solutions. Featuring a wide 2:1 input voltage range (33.6V to 48V DC), it provides a regulated 48V DC output with a maximum current of 4.2A. The device is built to meet stringent EN50155, IEC60571, IEC61373, and EN50121-3-2 standards, making it ideal for railway and vehicle power systems.
The chassis mount enclosure and semi-encapsulation protect the PCB against mechanical and environmental stresses, while the robust 4000V DC isolation voltage ensures safety and reliability in demanding industrial environments. Its high efficiency rating of up to 91% minimizes energy loss and heat generation, enabling convection cooling without fans.
Operating in a wide temperature range from -40°C to 70°C, the RSD-200C-48 is suitable for harsh conditions. The converter includes built-in short circuit, overload, over voltage, and over temperature protections to safeguard downstream equipment. An LED indicator provides clear power-on status, and the device withstands high vibration levels up to 5G, ensuring mechanical durability.
Compact dimensions of 191mm length by 40mm width and depth allow easy integration into control panels and enclosures. With a mean time between failures (MTBF) of 218,200 hours, this DC-DC converter is engineered for long-term reliability in transportation, industrial automation, and railway power conversion applications.
201.6W maximum output power ensures stable supply for critical loads. Wide 2:1 input voltage ratio supports 33.6V to 48V DC sources. Compliant with major railway and industrial safety and vibration standards. High 4000V DC isolation protects sensitive electronics.
Semiencapsulated, chassis mount design with LED power indicator. Extended operating temperature range from -40°C to 70°C. Multiple protection features safeguard against faults. High efficiency up to 91% for energy savings.
Compact form factor fits diverse industrial installations.
