About the MEAN WELL NDR-75-12
The MEAN WELL NDR-75-12 is a slim 75 W single-output industrial DIN-rail power supply designed for TS-35/7.5 or TS-35/15 mounting rails, providing a compact 32 mm width that saves valuable space in control cabinets. It delivers a stable 12 V DC / 6.3 A output with an adjustable range of 12–14 V, making it ideal for powering 12 V control electronics, sensors, relays, and low-voltage actuators. With high efficiency up to 85.5 % and fanless natural convection cooling, the unit supports reliable long-term operation from −20 °C to +70 °C without the need for additional fans. Its constant-current overload protection characteristic allows safe use with inductive and capacitive loads while automatically recovering after fault conditions are cleared. The robust metal housing, full-range universal AC input, integrated DC OK indication, and comprehensive industrial approvals make the NDR-75-12 a dependable and low-maintenance choice for factory automation and control systems.
