Mean Well MDR-100-24 DIN Rail Power Supply Module

The Mean Well MDR-100-24 DIN-Rail Power Supply is a compact industrial AC/DC switching module that outputs 24 VDC at 4.0 A (96 W) to power PLCs, HMIs, sensors, relays, and other 24 V control equipment in factory automation and process control panels. It accepts a wide input from 85–264 VAC / 120–373 VDC, mounts on TS35 DIN rails, and uses free-air convection cooling with an isolation rating of 3 kV. Typical efficiency is 86%. It features short-circuit, overload, over-voltage, and over-temperature protection, a DC OK relay contact, and a Power On LED indicator. Its dimensions are 55 × 100 × 90 mm, and operating temperature ranges from -10°C to +60°C (with derating). This single-output DIN-rail supply is designed for industrial automation, control panels, and PLC systems, delivering reliable 24 VDC power with built-in protections in a slim, easy-to-install package.
