Test conditions and notes6
- 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. 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 )
- 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 6. 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 LPP-100-3.3 for 3.3V embedded electronics or controller boards?
Yes, if the equipment requires a constant 3.3V DC source and the total load stays within 20A and 66W. This model is a constant voltage supply, which matches typical 3.3V electronics power requirements.
Is the LPP-100-3.3 suitable for powering 3.3V logic-heavy industrial electronics?
It can be a fit for 3.3V electronics that need high current at low voltage, because it delivers up to 20A at 3.3V. The total output limit is 66W, so the full system load needs to remain inside that rating.
Would this work for a 3.3V test bench or embedded development fixture?
It is suitable where a fixed 3.3V DC output is required and the demand stays at or below 20A. The wide 85-264VAC input range also helps when the fixture may be used on different AC mains sources.
Can the LPP-100-3.3 power a 3.3V communications or processing subsystem?
Yes, for subsystems built for constant 3.3V input and sized within 66W total power. Its 222.0 × 62.0 × 33.6 mm form factor can also be useful in narrow equipment housings.
Is the LPP-100-3.3 appropriate for outdoor or dusty environments?
The sheet lists an operating temperature range of -10°C to +60°C (refer to the derating curve), but no IP rating. Dust and water ingress protection is not specified, so it should be installed inside a protected enclosure rather than outdoors or in dusty areas.
