Test conditions and notes9
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. No minimum load required.
- 3. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 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. Tolerance : includes set up tolerance, line regulation and load regulation.
- 6. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 7. Touch current was measured from primary input to DC output.
- 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. 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-20-5 for a 5V single-board computer or industrial logic controller?
Yes, it supplies a constant 5V output up to 4A with a 20W power rating. That fits many 5V logic and computing loads as long as the device stays within those limits.
Is the MPM-20-5 suitable for powering USB-class 5V electronics inside OEM equipment?
It can be suitable where the internal electronics need a regulated 5V rail and the total demand does not exceed 4A or 20W. The compact 52.4 × 27.2 × 24.0 mm size helps in space-constrained assemblies.
Can this model support 5V HMI, sensor hub, or communications hardware in an automation cabinet?
It is intended for constant-voltage 5V loads, so it can support 5V control electronics and interface hardware within its 4A output current limit. The 80-264VAC input also makes it easier to use across different AC supply ranges.
Would the MPM-20-5 work for medical or test equipment that needs a low-voltage 5V rail?
This unit is medical safety approved, which makes it relevant for low-power medical or lab electronics using a 5V bus. The connected load still needs to fit inside the 20W and 4A rating.
Is the MPM-20-5 rated for outdoor or washdown conditions?
The operating temperature range is -35°C to +85°C, with output derating at higher ambient temperatures per the derating curve, but the specs do not list any IP rating. That means the product page does not state outdoor ingress protection, so it is best treated as a protected or enclosed-use supply unless the finished equipment provides that protection.
