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. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 5. 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 )
- 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 LPS-75-3.3 for a 3.3V embedded system with high current demand?
Yes, if the system requires a constant 3.3V supply and needs up to 15A. This model is rated for 49.5W, so it is suited to 3.3V loads that need more current than lower-output supplies can provide.
Is this power supply appropriate for powering 3.3V logic boards or industrial electronics?
It is appropriate for electronics designed for constant 3.3V DC input, provided the total load stays within 15A and 49.5W. That makes it relevant for logic-heavy embedded or control assemblies that operate at 3.3V.
Can the LPS-75-3.3 support a dense electronics assembly where space is limited?
Yes, its 222.0 x 55.0 x 30.0 mm dimensions and 0.3 kg weight help where the power section needs to stay compact. It still delivers up to 15A at 3.3V for higher-current low-voltage loads.
Would this model make sense for a 3.3V test fixture or burn-in rack?
It can, if the fixture is built around constant 3.3V DC and the connected load remains within 49.5W. The -20 degrees C to +70 degrees C operating range may also help in controlled industrial test environments.
Should the LPS-75-3.3 be used indoors or outdoors?
The listed operating temperature range is -20 degrees C to +70 degrees C, but no IP rating is given. Without an IP rating in the specs, it is better suited to indoor equipment or a protected enclosure.
