Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 400VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
  6. 6. Derating may be needed under low input voltage. Please check the derating curve for more details.
  7. 7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the WDR-480-24 for a 24V PLC cabinet with multiple devices?

Yes, this model is built for DIN rail industrial power applications where 24V DC is needed in a control cabinet. It delivers 480W at 24V with up to 20A output current, which suits higher-load 24V PLC and automation panels.

Is the WDR-480-24 a good fit for industrial automation panels with relays, sensors, and control components?

It is suitable for 24V DC industrial automation loads as long as the total requirement stays within 480W and 20A. The slim metal case supports DIN rail mounting in control enclosures where panel space matters.

Can this power supply be used in building management systems that standardize on 24V DC?

Yes, it can support building management and control systems that use a 24V DC bus and need more available current than smaller DIN rail units provide. The wide 180-550VAC input also fits facilities where input conditions vary across installations.

Can the WDR-480-24 be used inside a control enclosure in hotter or colder industrial areas?

It is intended for enclosed industrial cabinet use and has an operating temperature range of -30°C to +70°C. That range supports control enclosure applications across a broad set of indoor industrial conditions.

What are the main differences between the WDR-480-24 and other WDR series power supplies?

For 24V models, the WDR range includes WDR-60-24 at 60W, 2.5A; WDR-120-24 at 120W, 5A; WDR-240-24 at 240W, 10A; and WDR-480-24 at 480W, 20A. The rest of the sibling lineup is WDR-60-5 at 50W, 5V, 10A; WDR-60-12 at 60W, 12V, 5A; WDR-60-48 at 60W, 48V, 1.25A; WDR-120-12 at 120W, 12V, 10A; WDR-120-48 at 120W, 48V, 2.5A; WDR-240-48 at 240W, 48V, 5A; and WDR-480-48 at 480W, 48V, 10A.
