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 MFM-05-5 for a 5V embedded system or microcontroller board?

Yes, this model provides constant voltage 5V output rated at 5W and 1A. It is suited to low-power embedded boards and control electronics that need a regulated 5V supply within that output limit.

Is the MFM-05-5 suitable for small industrial HMI, interface, or sensor electronics?

It can be used for compact 5V interface, sensor, or logic circuits where 1A is enough. The PCB-type construction and 42.0 × 22.3 × 20.5 mm size also make it practical in space-constrained electronic assemblies.

Can this 5V supply work for low-power IT or communications hardware?

It can fit low-power 5V electronics used in IT or communications equipment if the load stays within 5W and 1A. The wide 80-264VAC input also supports use across common AC input ranges.

How does the MFM-05-5 compare to the other MFM models?

The MFM-05 series on this sheet covers outputs from 3.3V to 24V and from 4.1W to 5.5W. Related models are MFM-05-3.3 at 4.1W 3.3V 1.25A, MFM-05-12 at 5W 12V 0.42A, MFM-05-15 at 5W 15V 0.33A, and MFM-05-24 at 5.5W 24V 0.23A. All share the 80-264VAC input, the 42 × 22.3 × 20.5 mm size and 2xMOPP medical approval. The MFM-05-5 is the 5V, 5W, 1A version, offering the highest output current after the 3.3V model.

Can the MFM-05-5 be used in outdoor or washdown environments?

The specs show an operating temperature range of -40°C to +85°C (with derating at higher temperatures), but no IP rating is provided. That means thermal capability is specified, while outdoor water or dust protection is not stated in the product data.
