Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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 http://www.meanwell.com)
5. Mounting holes M1 and M2 should be grounded for EMI purposes.
6. Heat Sink HS1,HS2 can not be shorted.
7. Touch current was measured from primary input to DC output.

FAQ

Can I use the MPS-65-3.3 for 3.3V embedded controllers or logic boards?

Yes, if the electronics require constant 3.3V DC and the total current stays within 12A. This model is rated at 39.6W, which is substantial current for low-voltage digital loads. It should only be used with hardware specified for a 3.3V input rail.

Is the MPS-65-3.3 suitable for powering industrial computing or communication boards that run on 3.3V?

It can be a fit for industrial computing, communication, or processing boards designed around a 3.3V DC bus and drawing up to 12A. Because the output voltage is only 3.3V, exact voltage matching is critical. The supply operates from 90-264VAC input.

Can this model support low-voltage automation electronics with higher current demand?

It is better suited to low-voltage electronics that need more current rather than higher voltage, since it provides 3.3V at up to 12A. That can suit dense digital or embedded loads as long as the total power does not exceed 39.6W. It is not appropriate for 5V, 12V, 24V, or 48V systems.

How does the MPS-65-3.3 compare with the other MPS-65 models?

In the MPS-65 lineup, the available outputs are 3.3V 12A 39.6W, 5V 12A 60W, 7.5V 8A 60W, 12V 5.2A 62.4W, 13.5V 4.7A 63.45W, 15V 4.2A 63W, 24V 2.7A 64.8W, 27V 2.4A 64.8W, and 48V 1.35A 64.8W. This version is the lowest-voltage option and one of the highest-current outputs in the range. The correct choice depends on the exact DC voltage your electronics require.

Is the MPS-65-3.3 intended for indoor or outdoor conditions?

The product data specifies an operating temperature range of -10°C to +60°C. It does not provide an IP rating, so the listing does not indicate weather resistance or a sealed enclosure for outdoor exposure. On the stated specs alone, it is better considered for protected indoor use.
