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-20-15 for 15V industrial control or measurement electronics?

Yes, this is a constant-voltage 15V power supply rated for 1.4A and 21W, which fits low-power 15V industrial electronics. It is appropriate where the connected load remains within 1.4A and 21W.

Is the MFM-20-15 suitable for embedded OEM hardware that needs a regulated 15V rail?

It is designed as a PCB type supply and measures 49.0 x 23.8 x 23.0 mm, so it suits compact internal assemblies. Electrically, it delivers 15V constant voltage with up to 1.4A available current.

Would this model work for small analog, instrumentation, or control boards that run on 15V?

It can fit low-power 15V boards used in instrumentation or control equipment as long as the total demand does not exceed 21W. The supply accepts 80-264VAC input, which helps when the equipment may be used on different AC mains systems.

Can the MFM-20-15 be used in medical or lab equipment with modest 15V power needs?

It can be considered for low-power 15V equipment because it is medical safety approved (2 x MOPP) to IEC/EN 60601-1 and ANSI/AAMI ES60601-1, with CAN/CSA C22.2 No. 60601-1 and EAC TP TC 004 also listed. The output is limited to 15V at 1.4A, so the device load must stay within 21W.

Is the MFM-20-15 rated for outdoor exposure or extreme indoor temperatures?

The operating temperature range is -35C to +85C, with output derating required at higher ambient temperatures (see the derating curve). However, no IP rating is listed, so this model is not specified here for direct outdoor or unprotected wet-location use.
