Bloc d'alimentation MEAN WELL NDR-480-24

The MEAN WELL NDR-480-24 is an industrial AC-DC single-output DIN-rail power supply that provides 24 VDC at 20 A (480 W). Housed in a metal case and compliant with RoHS, it accepts a wide input voltage range of 90–264 VAC and features compact dimensions (85.5 mm W × 128.5 mm D × 125.2 mm H). Each pack contains 8 units.

Advantages

The DIN-rail design enables straightforward installation in control cabinets and industrial enclosures. A metal housing offers mechanical protection and heat dissipation. Wide input voltage range ensures compatibility with global mains supplies and reduces the need for additional input conditioning. RoHS compliance indicates the product meets restricted substance regulations.
