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 MFM-30-12 for 12V PLC accessories, relays, or industrial control boards?

Yes, this is a constant voltage 12V supply with up to 2.5A output, which suits many PLC accessories, relays, and compact control boards that operate from 12V DC. Keep the total load within the 30W rating; no minimum load is required.

Is the MFM-30-12 a good choice for embedded 12V equipment inside a machine enclosure?

It is well suited to embedded 12V electronics where a PCB type AC-DC supply is preferred and space still matters. The unit measures 65.5 x 35.0 x 23.0 mm and delivers 12V at up to 2.5A.

Can this model power small 12V automation modules that need more current than entry-level board supplies?

Yes, it supplies a constant 12V at up to 2.5A continuous (30W rated), with a 2.9A peak current for up to 10 seconds, which suits small 12V automation modules within that budget. No minimum load is required, so lightly loaded modules are also fine.

Does the MFM-30-12 handle wider temperature swings in protected equipment?

Its specified operating temperature range is -40C to +85C, with output derating at higher ambient temperatures according to the derating curve. No IP rating is given, so the temperature range should be read as an electrical operating limit for indoor protected equipment, not as proof of outdoor exposure resistance.

How does the MFM-30-12 compare with the other 12V models in the MFM series?

This datasheet covers one 12V model, the MFM-30-12 at 30W and 2.5A. The other MFM-30 outputs are MFM-30-3.3 at 19.8W, 3.3V, 6A; MFM-30-5 at 30W, 5V, 6A; MFM-30-15 at 30W, 15V, 2A; MFM-30-24 at 31.2W, 24V, 1.3A; and MFM-30-48 at 30.2W, 48V, 0.63A.
