MEAN WELL NDR-240-24 is a rugged 240 W DIN‑rail PSU that supplies a stable 24 V / 10 A rail for control panels, motion, and instrumentation. MEAN WELL NDR-240-24 supports 90–264 VAC (127–370 VDC) input and mounts to TS‑35 rails to streamline panel builds.
With typical efficiency around 88.5% and free‑air convection cooling, it performs reliably across demanding environments. Output quality is maintained with 150 mVp‑p ripple and a typical 28 ms hold‑up at 230 VAC to help ride through short sags. An adjustable 24–28 V range lets you compensate voltage drop on long runs.
Comprehensive protection includes constant‑current overload, over‑voltage, over‑temperature, and short‑circuit safeguards. Operating from −20 °C to +70 °C (derating), the metal enclosure of MEAN WELL NDR-240-24 saves space while enhancing heat dissipation.
