Test conditions and notes8
- 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. If the input range 85V-89V, the output load is changed from 0A-rated load, There will be reduced 20V for 1second (LPS-100-24).
- 6. Mounting holes M1 and M2 should be grounded for EMI purposes.
- 7. Testing harmonic current at 90% load.
- 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).

FAQ
Can I use the LPS-100-3.3 for 3.3V embedded processors, logic boards, or industrial electronics?
Yes, this model is designed for constant voltage output at 3.3V and can deliver up to 20A. That makes it a candidate for 3.3V logic-heavy electronics or embedded assemblies that need high current within the 66W limit.
Is the LPS-100-3.3 suitable for powering multiple 3.3V digital loads from one supply?
It can be suitable when the combined 3.3V load stays within 20A and 66W total output. The constant voltage design matches systems that require a fixed 3.3V rail for digital or control electronics.
Can this model be used for 3.3V industrial control logic or communication boards?
Yes, if those boards are specified for a direct 3.3V constant voltage source. Its 20A output capacity is useful for lower-voltage systems where current demand is higher even though the total power is 66W.
Is the LPS-100-3.3 a good fit where high current is needed at low voltage?
That is where this version stands out in the series, because it provides 3.3V at up to 20A. It is intended for applications that specifically need a low-voltage, high-current constant voltage supply rather than higher-voltage outputs.
Can the LPS-100-3.3 be used in outdoor or harsh exposed environments?
The listed operating temperature range is -10°C to +60°C, but no IP rating is provided in the specs. From the available product data, it is better aligned with protected indoor environments than exposed outdoor or washdown areas.
