Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 400VAC input, rated load and 25℃ of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
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. 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. Derating may be needed under low input voltage. Please check the derating curve for more details.
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-240-24 for a larger 24V PLC control cabinet?

Yes, this model is designed for 24V control panels that need more capacity, with a 240W output rating and 10A output current. It mounts on DIN rail and has a 63mm width, offering a compact profile for industrial cabinets.

Is the WDR-240-24 suitable for 24V industrial automation loads in one enclosure?

It is a good fit for 24V industrial automation cabinets where multiple 24V loads are grouped and the total demand stays within 240W. The 180-550VAC wide input supports use with single-phase and two-phase input systems.

Can this be used in a 24V building management panel with several control devices?

Yes, this power supply can serve 24V building management and control enclosures that require up to 10A at 24V DC. Compared with the 120W version, it provides more output current while keeping the same 125.2 × 113.5 mm footprint.

Is the WDR-240-24 appropriate when cabinet temperatures drop below -25°C?

Yes, this model is rated for -30°C to +70°C operation. That makes it suitable for protected control enclosures that may experience colder ambient conditions while still staying within the specified range.

What is the difference between the WDR-240-24 and other WDR DIN rail models?

The WDR family includes WDR-120-12 at 120W, 12V, 10A, WDR-120-24 at 120W, 24V, 5A, WDR-120-48 at 120W, 48V, 2.5A, WDR-240-24 at 240W, 24V, 10A, and WDR-240-48 at 240W, 48V, 5A. Larger models are WDR-480-24 at 480W, 24V, 20A and WDR-480-48 at 480W, 48V, 10A. Smaller models are WDR-60-12 at 60W, 12V, 5A, WDR-60-24 at 60W, 24V, 2.5A, WDR-60-48 at 60W, 48V, 1.25A, and WDR-60-5 at 50W, 5V, 10A.
