MEAN WELL XDR-240-48 DIN Rail Power Supply 48V 240W

Industrial control panels and automation systems often need a reliable 48V DC source that fits on a standard DIN rail without active cooling. The MEAN WELL XDR-240-48 delivers 240W of regulated 48V power with active PFC and a wide input range, making it suitable for machine builders and system integrators who require a compact, convection-cooled supply.

Who is it for

Engineers and technicians who install power supplies in electrical cabinets, especially where DIN rail mounting is standard and forced air cooling is not available. It serves PLC systems, sensor networks, motor drivers, and other industrial loads that demand stable 48V DC.

Tips

When adjusting the output voltage above 48V, ensure the connected load can handle the higher voltage. Mount the unit with adequate spacing for convection airflow, and derate the output power above 50°C ambient temperature according to the datasheet.
