MEAN WELL NDR-240-48 is a robust 240 W DIN‑rail PSU that delivers a stable 48 V / 5 A rail for motion, conveyors, and instrumentation. MEAN WELL NDR-240-48 supports 90–264 VAC (127–370 VDC) and mounts to TS‑35 rails to simplify cabinet builds.
Typical efficiency reaches ~90%. Output quality is kept high with 150 mVp‑p ripple and a typical 28 ms hold‑up at 230 VAC, helping your 48 V bus ride through short dips. The 48–55 V adjustment range allows compensation for voltage drop on long cables.
Protection covers constant‑current overload, over‑voltage, over‑temperature, and short‑circuit. Operating from −20 °C to +70 °C (derating), the metal enclosure of MEAN WELL NDR-240-48 saves panel space while aiding heat dissipation.
