MEAN WELL NDR-480-48 is a powerful 480 W DIN‑rail PSU that delivers a clean 48 V / 10 A rail for large control systems and motion applications. MEAN WELL NDR-480-48 operates from 90–264 VAC (127–370 VDC) and achieves 92.5% typical efficiency to reduce heat in dense cabinets.
Output quality is maintained with 150 mVp‑p ripple and a typical 16 ms hold‑up at both 115 and 230 VAC. Power‑factor performance helps meet harmonic limits, and the metal housing enhances thermal behavior and durability.
Protection is comprehensive: constant‑current overload (105–130%) with 3‑second shutdown/restart, over‑voltage 56–65 V, over‑temperature, and short‑circuit. Rated −20 °C to +70 °C (derating), MEAN WELL NDR-480-48 mounts to TS‑35 rails and meets industrial safety/EMC requirements for dependable 48 V power.
