High-Efficiency 240W Industrial Power on a Slim Profile
The Mean Well NDR-240-48 is an economical and slender 240W DIN rail power supply, specifically engineered for space-saving installation on TS-35/7.5 or TS-35/15 mounting rails. Its compact 63mm width makes it an ideal solution for crowded cabinets in industrial control systems, factory automation, and semi-conductor fabrication equipment. This unit accepts a universal AC input from 90VAC to 264VAC and is designed with a robust metal housing that enhances power dissipation. With an impressive efficiency of up to 90%, it operates reliably in ambient temperatures ranging from -20°C to +70°C under free air convection cooling.
Robust Performance and Comprehensive Protection
Engineered for demanding industrial applications, the NDR-240-48 features a built-in active PFC function and conforms to the European Union's standard for harmonic current, BS EN/EN61000-3-2. It is equipped with a suite of protections, including short circuit, overload, over voltage, and over temperature safeguards, ensuring the longevity of both the power supply and connected equipment. The constant current mode for overload protection makes it suitable for various inductive or capacitive loads. This power supply is UL 508 approved for industrial control equipment and has undergone a 100% full load burn-in test to guarantee reliability.
