  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.

FAQ

Can I use the MFM-10-3.3 to power a 3.3V embedded controller board?

Yes, this unit provides constant-voltage 3.3V output with up to 2.5A and 8.3W. That fits embedded controller boards, logic circuits, and low-voltage electronics that need a regulated 3.3V supply within that limit.

Is the MFM-10-3.3 a good fit for industrial IoT or communications electronics?

It can be a fit for industrial IoT and communications hardware that runs on 3.3V and draws no more than 2.5A or 8.3W. The wide 80-264VAC input also makes it suitable for internal AC-powered equipment designs.

Can this power supply be used in a small automation HMI or monitoring device?

Yes, for designs that need a 3.3V internal rail, this model is sized for compact equipment at 42.0 × 22.3 × 20.5 mm. Its PCB type and 0.018 kg weight make it practical for low-power automation or monitoring devices with tight internal space.

Can the MFM-10-3.3 be used in hot or cold operating conditions?

The specified operating temperature range is -30°C to +85°C, with output derating at higher temperatures per the derating curve. No IP rating is provided, so it is better suited to enclosed indoor assemblies than direct outdoor exposure.
