MEAN WELL EDR-120-12 is a slim 120 W DIN‑rail supply that provides a stable 12 V / 10 A rail for machinery, automation, and instrumentation. MEAN WELL EDR-120-12 supports 90–264 VAC (127–370 VDC) input and mounts to TS‑35 rails for fast integration.
Typical 85% efficiency and convection cooling suit compact panels. A DC‑OK LED confirms status, while the 12–14 V trim helps counter line drops on long runs. Ripple is contained to 100 mVp‑p, and hold‑up is typically 16 ms at 230 VAC to ride through brief sags.
Protection includes short‑circuit, constant‑current overload, over‑voltage (14–17 V), and over‑temperature. Operating −20 °C to +60 °C with derating, MEAN WELL EDR-120-12 balances size and reliability for 12‑volt control systems.
