Test conditions and notes5
- 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 0.1uf & 47uf 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.
- 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.

FAQ
Can I use the WDR-120-24 for a 24V PLC or HMI cabinet?
Yes, this model is suitable for 24V PLC and HMI control cabinets when the total 24V DC load does not exceed 120W or 5A. Its DIN rail mounting and 40.0 mm slim profile make it practical for narrow panel layouts.
Is the WDR-120-24 appropriate for 24V industrial automation controls?
It is a fit for 24V industrial automation panels that need a regulated 24V DC source up to 5A. The 180-550VAC input range supports use in systems with 1 phase or 2 phase input power.
Can this power a 24V building management control enclosure?
Yes, it can be used in 24V building management cabinets, relay panels, and monitoring enclosures as long as the connected load stays within 120W. The slim DIN rail package helps when cabinet space is limited.
Will this fit enclosed control cabinets that see temperature swings?
This power supply is intended for enclosed cabinet use and has an operating temperature range of -25°C to +70°C. The specs do not provide an outdoor IP rating, so it is best treated as a power supply for protected control enclosures.
What are the main differences between the WDR-120-24 and other WDR models?
For 120W models, the series includes WDR-120-12 at 12V, 10A, WDR-120-24 at 24V, 5A, and WDR-120-48 at 48V, 2.5A. Larger models 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. 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.
