MEAN WELL EDR-120-12 DIN-rail voeding 120W 12V 10A industriële schakelvoeding

Industrial control panels and building automation systems often demand a reliable power source that can be mounted directly onto a DIN rail, withstand harsh electrical environments, and deliver stable DC output without interruption. The MEAN WELL EDR-120-12 answers that need with a robust 120-watt switching power supply engineered for continuous operation in demanding applications. It converts a universal AC input of 90-264VAC (or 127-370VDC) into a tightly regulated 12V DC output at up to 10 amps, making it ideal for powering sensors, PLCs, relays, and other automation components.

Who is it for

This power supply is built for system integrators, panel builders, and maintenance engineers who need a compact, DIN rail mountable unit that meets international safety and EMC standards. Its metal housing and free air convection cooling ensure durability without the need for fans, reducing maintenance and noise in control cabinets. The adjustable output voltage (10.8-13.8V) allows fine-tuning for specific load requirements, while comprehensive protection features guard against short circuits, overloads, over voltage, and over temperature.

Tips

When installing the EDR-120-12, ensure adequate ventilation around the unit to allow free air convection. For applications requiring a different output voltage, use the built-in potentiometer to adjust within the specified range. Always verify that the total load does not exceed 120W to maintain reliable operation and long service life.
