The MEAN WELL NDR-120-12 is a compact and highly reliable 120 W industrial DIN rail AC/DC power supply designed to provide stable 12 V DC power for industrial control, automation and electrical systems. As part of the established MEAN WELL NDR-120 series, it combines a slim metal enclosure with universal AC input and comprehensive electrical protection.
This single-output power supply delivers up to 10 A at 12 V DC and incorporates short-circuit, overload, overvoltage and overtemperature protection. Its 40 mm-wide housing helps conserve valuable cabinet space, while free-air convection cooling eliminates the need for an internal cooling fan.
With a universal 90–264 V AC single-phase input and support for 127–370 V DC input, the NDR-120-12 is suitable for a broad range of industrial power systems. Its adjustable 12–14 V DC output, TS-35 DIN rail mounting and industrial immunity characteristics make it particularly suitable for control panels, factory automation equipment and electromechanical systems.
Industrial DIN rail power supplies such as the MEAN WELL NDR-120-12 convert incoming AC mains power into a regulated DC supply for control and automation equipment. Its stable 12 V DC output can supply PLC-related equipment, sensors, relays, control devices and other industrial loads requiring up to 10 A.
The NDR-120 series is engineered for industrial control environments where reliability, cabinet space and straightforward installation are important. Its metal housing, fanless convection cooling, comprehensive protection functions and industrial EMC immunity make the NDR-120-12 a practical power solution for both new control systems and replacement applications.
