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-15-12 for a 12V PLC accessory or control circuit?

Yes, this model provides constant-voltage 12V output with up to 1.25A and 15W. That suits low-power PLC accessories, control boards, and industrial electronics that require a 12V rail within those limits.

Is the MFM-15-12 suitable for 12V automation sensors, relays, or interface boards?

It can be used where the combined 12V load does not exceed 1.25A or 15W. Its PCB construction and compact 49.0 × 23.8 × 23.0 mm size are intended for internal mounting in control and automation equipment.

Can this power supply be used in medical or diagnostic equipment?

The listed features include medical safety approval and extremely low leakage current. It can therefore be considered for low-power internal 12V sections of medical or diagnostic equipment up to 15W, while final equipment compliance still depends on the complete end product.

Will the MFM-15-12 handle cold or high-temperature indoor environments?

The operating temperature range is -35°C to +85°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is given in the provided specs, so it should be treated as an enclosed PCB power supply rather than an exposed outdoor unit.
