The Mean Well SDR-120-48 is a 120 W industrial DIN-rail power supply providing a 48 V DC output. It is designed for industrial automation systems, control cabinets, and other industrial equipment.

The unit features built-in active power factor correction (PFC) and high efficiency up to ≈90.5%. It supports 150% peak load capability, making it suitable for applications with temporary high current demand. Cooling is achieved by free air convection, ensuring reliable and maintenance-free operation.

The power supply includes comprehensive protection against short circuit, overload, over-voltage, and over-temperature. It can be mounted on a standard TS-35 DIN rail and includes a DC OK relay contact for monitoring output status.
