Mean Well NDR-480-24 480W 20A 24VDC Single Output AC to DC DIN Rail Power Supply (NDR Series Economical Model EMC EN55022 Class B)

The NDR-480-24 is a high-performance 480W industrial DIN rail power supply designed for demanding applications. With a 24V DC output and 20A rated current, it can provide stable power over a 0-20A load range while maintaining 1.0 % voltage accuracy. The device uses a universal 90-264VAC/127-370VDC input (47-63Hz), has a typical efficiency of up to 92.5 %, and is equipped with active PFC (PF> 0.98 @115VAC, PF> 0.94 @230VAC) for optimal energy utilization. The compact 85.5 mm width chassis supports TS-35/ 7.5 or TS-15 rail mounting, making it ideal for space-constrained control cabinets.

Key specifications include adjustable output voltage (24-28V), low ripple and noise (<150mVp-p), 0.5 % line regulation, 1.0 % load regulation, and fast response with 100ms rise time (1500ms start-up time at 230VAC). Designed for industrial environments, the power supply offers comprehensive protection: short circuit/overload/overvoltage/overtemperature protection, and 16ms hold-up time during power interruption. The power supply complies with UL 508 standards for industrial control equipment and BS EN/EN61000-6-2 EMI standards, and meets stringent EU harmonic current requirements (BS EN/EN61000-3-2). Operational reliability is ensured by 100% full load burn-in testing and natural convection cooling (-20C to +70C operation). Other features include <2mA leakage current, 35A surge current handling capability (@230VAC), and reinforced insulation. This maintenance-free solution is ideal for factory automation, process control systems and heavy machinery, and comes with a 3-year warranty, giving you peace of mind in industrial deployments.
