Test conditions and notes6
  1. 1. All parameters NOT specially mentioned are measured at 230VAC 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
  6. 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 MDR-40-5 for 5V PLC logic, controller boards, or industrial electronics?

Yes, this model is suited to 5V DC loads up to 6A, with a listed power rating of 30W. It is appropriate for DIN rail control panels where the electronics specifically require a 5V supply.

Is the MDR-40-5 a good fit for 5V modules inside a control cabinet?

It can be used for grouped 5V industrial electronics as long as the combined draw stays within 30W and 6A. The DIN rail format and 40 mm wide housing help when several components must fit in one enclosure.

Can this 5V power supply be used in building management or automation panels with low-voltage control electronics?

Yes, if the panel includes 5V DC devices and the total load remains within the unit's 30W and 6A output limits. The 85-264VAC input range also suits AC-fed control panels used in automation and facility systems.

Is the MDR-40-5 suitable when I need a slim DIN rail power supply for compact panel layouts?

Yes, the housing measures 40 x 90 x 100 mm (W x H x D) and mounts on TS-35/7.5 or TS-35/15 DIN rail. That makes it useful in compact DIN rail assemblies where a 5V supply must fit into limited panel space.

Should the MDR-40-5 be mounted in an enclosure rather than an exposed location?

This unit is generally intended for use inside a control cabinet or enclosure. The listed operating temperature range is -20C to +70C with output derating at higher ambient temperatures (see the derating curve), and no separate outdoor or washdown protection rating is included in the provided specs.

How does the MDR-40-5 compare with the other MDR series models?

Within the MDR-40 series, the MDR-40-5 is the 5V version at 30W and 6A. The other versions are MDR-40-12 at 12V, 40W and 3.33A, MDR-40-24 at 24V, 40.8W and 1.7A, and MDR-40-48 at 48V, 39.8W and 0.83A. The 5V model has 78% typical efficiency versus 85-88% for the others, and all share the 85-264VAC input and 40 x 90 x 100 mm DIN rail housing.
