Description
The MEAN WELL NDR-120-24 is a high-efficiency, single-output industrial DIN rail power supply designed for space-constrained automation environments. Belonging to the NDR-120 series, this unit features a slim 40mm width metal housing, allowing for high-density installation on TS-35/7.5 or TS-35/15 mounting rails. It utilizes Original Engineering to accept a universal AC input range (90-264VAC) and converts it to a regulated 24V DC output with 89% efficiency. The design incorporates active power factor correction and comprehensive protection circuitry against short circuit, overload, over voltage, and over temperature. This unit relies on free air convection for cooling, eliminating the need for mechanical fans and increasing long-term reliability. Technical Compatibility is guaranteed for industrial control systems, semiconductor fabrication equipment, and electro-mechanical apparatus requiring stable DC power in harsh environments.
