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 cold first 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-20-5 for 5V control electronics in an industrial panel?

Yes, it is suitable for industrial panel electronics that require 5V DC up to 3A. Its 15W output makes it a fit for lower-power 5V control loads mounted on DIN rail inside an enclosure.

Is the MDR-20-5 appropriate for PLC support circuits or interface boards that need 5V DC?

It can be used where PLC support circuits, interface boards, or other automation electronics require 5V DC and the total draw stays within 3A. The ultra slim 22.5 mm profile helps conserve DIN rail space in compact cabinets.

Can this 5V DIN rail power supply be used in building management control cabinets?

Yes, it can be used in building management control cabinets when the 5V devices stay within the 15W output rating. The 85-264VAC input also allows it to be fed from a wide standard AC input range.

How does the MDR-20-5 compare with other 5V MDR models?

This datasheet covers the MDR-20 series, in which the MDR-20-5 is the only 5V model, rated 15W and 3A. The other versions are the MDR-20-12 (12V, 20W, 1.67A), MDR-20-15 (15V, 20W, 1.34A) and MDR-20-24 (24V, 24W, 1A), all in the same 22.5 mm wide DIN rail housing.

Is the MDR-20-5 meant for open environments or enclosed control cabinets?

This model is best used inside protected control cabinets and enclosures rather than exposed locations. Its operating temperature range is -20°C to +70°C with output derating at higher temperatures per the derating curve, so enclosure conditions should stay within that range.
