The MEAN WELL EDR-120-12 is a slim and economical 120 W industrial DIN rail power supply designed to provide reliable DC power for factory automation, control panels and industrial electrical equipment. As part of the MEAN WELL EDR-120 series, it combines a compact 40 mm-wide metal enclosure with universal AC input capability and dependable protection functions.
This single-output switched-mode power supply delivers a regulated 12 V DC output at up to 10 A. Its output voltage can be adjusted from 12–14 V DC, providing additional flexibility when commissioning compatible equipment. The EDR-120 series uses free-air convection cooling, eliminating the need for an internal cooling fan while supporting reliable industrial operation.
With a universal 90–264 V AC single-phase input and rated output power of 120 W, the EDR-120-12 is well suited to PLC systems, relays, sensors, control equipment and other 12 V DC industrial loads. Its narrow enclosure mounts directly onto standard TS-35/7.5 or TS-35/15 DIN rail, helping conserve valuable space inside electrical control cabinets.
DIN rail switched-mode power supplies convert incoming mains power into a stable DC voltage required by industrial control equipment. The MEAN WELL EDR-120-12 provides a regulated 12 V DC supply with up to 10 A of output current, making it suitable for powering a broad range of compatible automation, control and electrical devices.
The EDR-120 series is designed with industrial control cabinets in mind. Its slim metal enclosure occupies only 40 mm of DIN rail width, while universal input capability, fanless cooling and comprehensive electrical protection help provide dependable operation in factory automation and electromechanical systems.
