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 the MFM-15-5 power a 5V single-board computer or embedded controller?

It can power 5V embedded electronics because it provides a constant 5V output rated at 3A and 15W. That makes it appropriate for board-level systems, controllers, or digital assemblies whose total demand stays within 3A.

Is this 5V power supply suitable for USB-level industrial electronics or gateways?

For equipment designed around a regulated 5V input, this model fits low-power industrial electronics and compact gateway hardware. The key limits are its 5V output, 3A maximum current, and 15W total power.

Can I use the MFM-15-5 for low-voltage automation boards inside a control enclosure?

Yes, for internal automation electronics that require 5V constant voltage, this model is a reasonable fit. It is a PCB type unit with 49.0 x 23.8 x 23.0 mm dimensions and supports up to 3A output current.

Would this model work for medical or lab devices with a small 5V internal load?

It can be considered for low-power 5V equipment because it is medical safety approved (2 x MOPP) to IEC/EN 60601-1 and ANSI/AAMI ES60601-1, and is EAC TP TC 004 approved. Output capacity is 15W at 5V, so the connected device must remain at or below 3A.

Is the MFM-15-5 meant for outdoor use or wide-temperature indoor equipment?

Its operating temperature range is -35C to +85C, with output derating at higher ambient temperatures per the derating curve, which supports demanding indoor ambient conditions. However, no IP rating is listed, so this product is not specified here for direct outdoor or exposed wet-environment use.

How does the MFM-15-5 compare to the other 5V versions in the MFM family?

In the MFM-15 series, the MFM-15-5 is the only 5V model, rated 15W and 3A with 85.5% typical efficiency. The other MFM-15 outputs are 3.3V at 11.6W and 3.5A, 12V at 15W and 1.25A, 15V at 15W and 1A, and 24V at 15.1W and 0.63A.
