Test conditions and notes6
- 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. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quick may lead to increase of the set up time.
- 6. 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-120-12 in a 12V PLC control cabinet?
Yes, this model is suited to 12V industrial control panels and PLC cabinets that need a 12V DC supply up to 10A. Its DIN rail form factor and 40.0 mm slim width help it fit into space-constrained control enclosures.
Is this a good choice for 12V industrial automation devices in a DIN rail panel?
It is appropriate for 12V industrial automation equipment when the total load stays within 120W and 10A. The wide 180-550VAC input also makes it suitable for panels using 1 phase or 2 phase input power.
Can this power a 12V building management or control panel assembly?
Yes, it can be used in 12V building management and control cabinet applications where the connected devices require 12V DC and the combined demand does not exceed 120W. The metal case and DIN rail design are aligned with enclosed industrial panel use.
Is the WDR-120-12 meant for open-air use or for control cabinets?
This unit is better suited to indoor control cabinets and electrical enclosures rather than exposed locations. The provided specs list a metal case, DIN rail format, and an operating range of -25°C to +70°C, but no outdoor IP rating is provided.
How does the WDR-120-12 compare with other WDR series models?
Within the series, the closest same-power siblings are WDR-120-24 at 120W, 24V, 5A and WDR-120-48 at 120W, 48V, 2.5A. Higher-power options are WDR-240-24 at 240W, 24V, 10A, WDR-240-48 at 240W, 48V, 5A, WDR-480-24 at 480W, 24V, 20A, and WDR-480-48 at 480W, 48V, 10A. Lower-power options are WDR-60-12 at 60W, 12V, 5A, WDR-60-24 at 60W, 24V, 2.5A, and WDR-60-48 at 60W, 48V, 1.25A.
