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 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the static characteristics for more details.
5. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
6. 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
7. 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).

FAQ

Can I use the EPS-65-3.3-C for a 3.3V OEM control assembly with higher current demand?

Yes, if the assembly needs a constant 3.3V output and the load stays within 11A and 36.3W. That makes it suitable for 3.3V control electronics, processor boards, and embedded assemblies with heavier low-voltage current draw.

Is the EPS-65-3.3-C a fit for industrial computing or logic-level electronics that run on 3.3V?

It can be used where the end device is designed for a fixed 3.3V input and requires up to 11A. The rated output power at 3.3V is 36.3W, with a 39.6W peak load allowed for 10 seconds.

Can this model power 3.3V monitoring, sensing, or automation boards inside machinery?

Yes, for 3.3V constant-voltage boards and electronics whose combined demand is no more than 11A. Its 90-264VAC input also suits equipment that may be deployed across different AC mains ranges.

Is the EPS-65-3.3-C suitable for outdoor use?

The listed operating range is -30°C to +70°C (per the output load derating curve), but no IP rating is provided in the specs. That points to use in protected indoor equipment or enclosures rather than direct outdoor exposure.

What is the difference between EPS-65-3.3-C and the other 3.3V EPS power supplies?

Within the EPS-65 series on this datasheet, the 3.3V options are EPS-65-3.3 and EPS-65-3.3-C, both rated 3.3V, 11A and 36.3W. EPS-65-3.3 is the 101.6 × 50.8 × 29.0 mm PCB version at 0.15 kg, while EPS-65-3.3-C is 103.4 × 62.0 × 37.0 mm at 0.3 kg; other EPS series are not covered by this sheet.
