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-240-48 for a 48V control panel or industrial automation cabinet?

Yes, this model is intended for DIN rail control cabinet use where a 48V DC output is required. It provides 240W at 48V with 5A output current, and its slim metal case is sized for rail-mounted panel layouts.

Is the WDR-240-48 suitable for building management or access control equipment that runs on 48V DC?

It can fit building management or access control systems that require a 48V DC supply and stay within 240W and 5A. The DIN rail format and 125.2 × 113.5 × 63.0 mm housing make it appropriate for organized enclosure installations.

Can this 48V DIN rail power supply be used for industrial communication or network devices inside a panel?

It is suitable for panel-mounted industrial equipment that needs 48V DC, provided the connected load does not exceed 240W or 5A. The wide 180-550VAC input also helps when the supply is used in industrial control environments with different AC input conditions.

Is the WDR-240-48 meant for open-air use, or should it be installed inside an enclosure?

This unit is better suited to protected control cabinets or enclosures rather than exposed open-air locations. Its operating temperature range is -30°C to +70°C, and the DIN rail metal-case design is aimed at enclosed industrial panel use.

How does the WDR-240-48 compare with other Mean Well WDR series models?

Within the WDR series, 48V options are WDR-60-48 at 60W, 1.25A; WDR-120-48 at 120W, 2.5A; WDR-240-48 at 240W, 5A; and WDR-480-48 at 480W, 10A. Other siblings include WDR-60-12 at 60W, 12V, 5A; WDR-60-24 at 60W, 24V, 2.5A; WDR-120-12 at 120W, 12V, 10A; WDR-120-24 at 120W, 24V, 5A; WDR-240-24 at 240W, 24V, 10A; and WDR-480-24 at 480W, 24V, 20A.
