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 MPM-05-3.3 for a 3.3V embedded controller or logic board?

Yes, if the board needs a constant 3.3V supply and draws no more than 1.25A or 4.1W. That makes it suitable for low-power embedded control, industrial logic, and sensor-processing circuits that run from an 80-264VAC input.

Is the MPM-05-3.3 a good fit for 3.3V IoT or industrial monitoring electronics?

It fits 3.3V monitoring or embedded electronics when total load stays within 1.25A and 4.1W. The encapsulated construction and compact 45.7 × 25.4 × 21.5 mm size can help in dense control assemblies.

Can this model power a low-power 3.3V communications or interface module?

It can, provided the module requires constant-voltage 3.3V power and remains under 1.25A. This model is better suited to low-power interface, control, or automation electronics than to larger 3.3V loads that need more than 4.1W.

Does the MPM-05-3.3 work in hot or cold environments?

The specified operating temperature range is -40°C to +85°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is listed, so the product data does not present it as an exposed outdoor power supply.

What other MPM models are closest to the MPM-05-3.3?

The closest 5W-class siblings are MPM-05-5 at 5W, 5V, 1A; MPM-05-12 at 5W, 12V, 0.42A; MPM-05-15 at 5W, 15V, 0.33A; and MPM-05-24 at 5.5W, 24V, 0.23A. All share the 80-264VAC input and the same 45.7 × 25.4 × 21.5 mm encapsulated package.
