MEAN WELL EDR-120-24 is a slim, industrial DIN-rail power supply providing a clean 24 V DC, 5 A output for control panels, PLCs, sensors, and HMIs. With a wide 90–264 VAC input range and high efficiency, it keeps 24 V buses stable while saving panel space. The metal housing snaps onto TS-35/7.5 or TS-35/15 rails for fast installation and dependable thermal performance.
Features include a front DC-OK LED for at-a-glance status, adjustable 24–28 V output to compensate for voltage drop, low ripple for sensitive loads, and a typical 16 ms hold-up time at 230 VAC. Built-in protections—short-circuit, overload, over-voltage, and over-temperature—safeguard downstream devices and minimize unplanned downtime.
Rated for –20 °C to +60 °C operation with derating, the MEAN WELL EDR-120-24 suits packaging lines, conveyors, building automation, textile equipment, and general 24 V instrumentation. Use correct clearances for airflow and follow wiring best practices for long service life. Choose MEAN WELL EDR-120-24 to upgrade your cabinet with compact size, proven safety approvals, and reliable industrial power. Mean Well
