DIN Rail Switching Power Supply – MEAN WELL SDR-480-24
The SDR-480-24 is a single-output DIN rail switching power supply (“Single Output DIN Rail Switching Power Supply”) manufactured by MEAN WELL, part of the SDR series. It delivers 480 W nominal output power at 24 V DC with a maximum current of 20 A. The input is universal (90–264 V AC, 47–63 Hz), featuring active power factor correction (active PFC) and an integrated fan for forced-air cooling. Output voltage is adjustable in the range 22–27 V DC via trimmer. Widely used as the primary power supply in CNC control cabinets, machine tools, industrial automation systems, and 24 V DC distribution applications.
The power supply is the component that converts AC mains voltage into stable DC voltage to power the CNC control logic, I/O modules, operator panels, and auxiliary components in the electrical cabinet. A power supply failure instantly halts the entire machine control chain: the CNC loses its reference, axes stop safely, and the machine cannot resume its cycle until the component is replaced or repaired. The stability of the DC supply voltage directly affects the reliability of inter-module communication and axis positioning accuracy.
MEAN WELL is a Taiwanese switching power supply manufacturer founded in 1982, one of the largest and most widely used producers of standard power supplies in industrial and automation applications worldwide. Its products carry UL, CE, and TÜV certifications and are extensively used in electrical cabinets, CNC machines, and embedded systems. The SDR series is currently in active production.
