Mean Well NDR-120-48 DIN Rail Power Supply 48 V 2.5 A 120 W

Industrial DIN Rail Power Supply

The Mean Well NDR-120-48 is a single-output industrial DIN rail power supply delivering 48 VDC at 2.5 A for a total of 120 W. It accepts a wide AC input range of 90 to 264 VAC at 47 to 63 Hz, making it suitable for global industrial installations. The unit mounts on standard DIN rails inside control cabinets or enclosures. It provides regulated DC power for automation, sensors, and control circuits.

Replaces older linear or lower-wattage supplies

This 120 W model replaces older linear supplies or lower-capacity switch-mode units that cannot meet the 48 V 2.5 A requirement. The wide 90 to 264 VAC input tolerates unstable mains without external tap changes. The jump is worth it when a compact DIN rail form factor and 120 W continuous output are needed for 48 V loads. It simplifies wiring by eliminating bulky transformers and separate regulators.

Suits panel builders and automation integrators

This supply suits panel builders and automation integrators powering 48 V PLCs, I/O modules, or sensor networks from a DIN rail. It is not for applications requiring redundant or parallel operation, adjustable voltage, or output signalling contacts. Buyers needing higher current, multiple outputs, or battery-backup integration should look at other series. The fixed 48 V output also rules out variable-voltage test bench use.
