Test conditions and notes9
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. No minimum load required.
  3. 3. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  4. 4. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
  5. 5. Tolerance : includes set up tolerance, line regulation and load regulation.
  6. 6. Derating may be needed under low input voltages. Please check the derating curve for more details.
  7. 7. Touch current was measured from primary input to DC output.
  8. 8. 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).
  9. 9. 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 )

FAQ

Can I use the MPM-20-12 to power a 12V PLC accessory or industrial control circuit?

Yes, it provides constant-voltage 12V output up to 21.6W and 1.8A, which fits low-power 12V control electronics that stay within those limits. The 80-264VAC input also makes it flexible for different AC supply regions.

Is the MPM-20-12 suitable for 12V instrumentation or automation sensors in a compact machine enclosure?

It can be a fit for enclosed 12V instrumentation and automation loads that need up to 1.8A. The encapsulated design and 52.4 x 27.2 x 24.0 mm size help where available space is tight.

Can this model be used in medical or monitoring equipment that runs on 12V?

It can be used for low-power 12V monitoring or medical devices when the load remains within 21.6W. The listed features include medical safety approval and extremely low leakage current, which are relevant for that kind of equipment.

Is the MPM-20-12 outdoor-rated, or is it better for protected indoor equipment?

The operating temperature range is -35C to +85C, with output derating at higher ambient temperatures per the derating curve, so it can handle broad equipment temperatures in a protected enclosure. No IP rating is stated, so the specs do not support calling it outdoor-rated or waterproof.
