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-20-15 for 15V equipment in a control cabinet?

Yes, it is suitable for control cabinet applications that require 15V DC up to 1.34A. With a 20W rating and DIN rail format, it fits lighter-load industrial power distribution inside enclosures.

Is the MDR-20-15 appropriate for PLC or industrial automation systems that use 15V DC?

It can be a fit for PLC or automation subsystems that specifically require 15V DC and draw no more than 1.34A. The ultra slim 22.5 mm profile is useful where DIN rail space is tight.

Can this 15V DIN rail power supply be used for building management panels?

Yes, it can be used in building management panels where the controls or interface devices are designed for 15V DC and stay within 20W. The 85-264VAC input range also gives flexibility for standard AC-fed panel installations.

How does the MDR-20-15 compare with other MDR series options?

Within the MDR-20 series, the MDR-20-15 delivers 15V at up to 1.34A (20W). The other models on the same datasheet are the MDR-20-5 (5V, 15W, 3A), MDR-20-12 (12V, 20W, 1.67A) and MDR-20-24 (24V, 24W, 1A), all sharing the same 22.5 mm wide DIN rail housing.

Is the MDR-20-15 meant for exposed locations or enclosed industrial panels?

This model is better suited to protected industrial panels and control enclosures than exposed locations. Its rated operating temperature range is -20°C to +70°C with output derating at higher temperatures per the derating curve, so the enclosure should remain within that range.
