NDR-240-24 MEAN WELL 240W 24V Single Output Industrial DIN-Rail Power Supply
The NDR-240-24 MEAN WELL is a high-performance, ultra-slim 240W AC/DC DIN-rail power supply designed for demanding industrial control systems, factory automation, and heavy marine electronic installations. Delivering a continuous 24V DC output at 10A, the NDR-240-24 MEAN WELL features a narrow 63 mm wide metal housing that optimizes space on standard TS-35/7.5 or TS-35/15 DIN rails within electrical cabinets.
Equipped with a universal single-phase AC input range ($90–264\text{ VAC}$) and built-in active Power Factor Correction (PFC, $\text{PF} > 0.95$), the NDR-240-24 MEAN WELL complies with stringent harmonic current standards (BS EN/EN61000-3-2). Featuring an exceptional high-efficiency rating of up to 88.5% and free-air convection cooling across an extended operating temperature range (-20°C to +70°C), it serves as a robust, long-term power foundation for PLCs, industrial gateways, high-current solenoid actuators, and SCADA systems.
Key Features of the NDR-240-24 MEAN WELL
-
Built-in Active PFC Function: Active power factor correction ($\text{PF} > 0.98$ at 115VAC, $\text{PF} > 0.95$ at 230VAC) reduces reactive power draw and meets global EMC regulations.
-
Slim Industrial Metallic Form Factor: Compact 63 mm width saves significant horizontal space inside high-density control panels and equipment racks.
-
High Efficiency Operation: Reaches up to 88.5% efficiency, minimizing thermal dissipation and lower operating costs within sealed enclosures.
-
Trimmable Output Voltage: Front-accessible DC voltage adjustment potentiometer allows output tuning from 24V to 28V DC to offset transmission line drops.
-
Complete Industrial Protection Suite: Includes short circuit, overload (constant current limiting mode), overvoltage, and overtemperature protections.
-
Heavy-Duty Compliance: Certified to UL508, TUV BS EN/EN62368-1, and BS EN/EN55032 Class B electromagnetic immunity and emissions standards.
Primary Applications
-
Heavy Factory Automation & Robotics: Supplying 24V DC power to large PLC racks, servo drives, motor starters, and high-density relay banks
-
Marine Telemetry & Shipboard Cabinets: Supplying clean power to multi-channel engine monitors, SCADA servers, and navigation backbones
-
Power & Renewable Energy Systems: Operating inside solar, wind, and substation control cabinets as a primary 24V DC auxiliary power supply
