MEAN WELL XDR-480E-48 – 480W 48V 10A Ultra-Slim DIN Rail Switching Power Supply
The MEAN WELL XDR-480E-48 is a high-performance 480W AC/DC industrial switching power supply designed for DIN rail installation in industrial automation, control systems, machinery, and other demanding applications requiring a reliable 48V DC power source.
Featuring a 48V DC output, 10A rated current, and an adjustable output voltage range of 48–55V DC, this power supply provides stable and efficient power for a wide range of industrial electronic equipment.
With an outstanding typical efficiency of 96%, the XDR-480E-48 minimizes energy losses and heat generation while maintaining dependable performance.
Its ultra-slim 48mm-wide housing allows efficient use of space inside electrical cabinets and control panels, making it particularly suitable for installations where mounting space is limited.
The integrated active power factor correction (PFC) improves power efficiency and reduces reactive power consumption.
The power supply supports parallel operation using droop current-sharing technology, allowing multiple compatible units to be connected to increase overall system capacity, up to 1920W with a 3+1 configuration.
A built-in DC OK relay contact enables remote monitoring of the output voltage status, making it suitable for industrial monitoring and automation systems.
The fanless design ensures silent operation and reliable cooling through natural air convection, eliminating mechanical fan wear and reducing maintenance requirements.
Its robust industrial construction supports operation in ambient temperatures from -40°C to +70°C, subject to derating.
Integrated protection against short circuits, overload, overvoltage, and overheating helps ensure safe and reliable operation.
