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-05-12 for a small medical or monitoring PCB that needs 12V AC-DC power?

Yes, this PCB-type power supply provides a constant 12V output and carries medical safety approval in the listed features. It is intended for low-power loads up to 5W and 0.42A.

Is the MFM-05-12 suitable for compact embedded or IT hardware with very low standby demand?

It is designed for compact installations with dimensions of 42.0 x 22.3 x 20.5 mm and a weight of 0.018 kg. The listed no load power consumption is less than 0.075W, which is useful when minimizing idle draw matters.

Can this 12V power supply run a low-power industrial interface board directly from mains input?

It accepts 80-264VAC input and delivers constant 12V output, so it fits low-power boards intended for that voltage. The load needs to stay within 5W and 0.42A.

Is the MFM-05-12 appropriate for harsh indoor temperature conditions?

The specified operating temperature range is -40 degrees C to +85 degrees C, with output derating at higher ambient temperatures per the derating curve. No IP rating is provided, so the product data does not identify it as suitable for exposed outdoor locations.

How does the MFM-05-12 compare with other MFM family options?

Within the MFM-05 series on this sheet, outputs range from 3.3V to 24V and power ranges from 4.1W to 5.5W: MFM-05-3.3 at 4.1W and 1.25A, MFM-05-5 at 5W and 1A, MFM-05-12 at 5W and 0.42A, MFM-05-15 at 5W and 0.33A, and MFM-05-24 at 5.5W and 0.23A. The MFM-05-12 is the 12V version.
