Test conditions and notes5
- 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. 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-150-3.3 to power 3.3V embedded controllers or digital electronics?
Yes, this model provides a constant 3.3V output and up to 30A. It is suited to 3.3V embedded, logic, or controller loads that need a high-current DC source within its 99W rating.
Is the LPP-150-3.3 a good fit for a 3.3V industrial test bench or burn-in setup?
It can fit 3.3V industrial electronics testing because it delivers up to 30A at 3.3V from an 85-264VAC input. The key limit is the 99W output rating, so the combined 3.3V load must stay within that published capacity.
Can this power supply support high-current 3.3V control boards in an automation system?
Yes, the main strength of this model is high current at low voltage: 30A at 3.3V. That makes it relevant for automation or embedded assemblies built around 3.3V rails rather than higher-voltage DC buses.
How does the LPP-150-3.3 compare with other LPP series versions?
Within the LPP-150 series, the other models are LPP-150-5 at 150W, 5V, 30A; LPP-150-7.5 at 150W, 7.5V, 20A; LPP-150-12 at 150W, 12V, 12.5A; LPP-150-13.5 at 151.2W, 13.5V, 11.2A; LPP-150-15 at 150W, 15V, 10A; LPP-150-24 at 151.2W, 24V, 6.3A; LPP-150-27 at 151.2W, 27V, 5.6A; and LPP-150-48 at 153.6W, 48V, 3.2A. All share the 85-264VAC universal input, active PFC and 222*75*41mm size. The LPP-150-3.3 is the 99W, 3.3V, 30A version in that range.
Can the LPP-150-3.3 be used where ambient temperatures vary?
The published operating temperature range is -10°C to +60°C with a cooling fan, subject to the derating curve (the sheet gives curves with an 18CFM fan and with no fan, where the load must be derated; 3.3V-7.5V models derate further under 100VAC with no fan). The provided specs do not include an IP rating, so outdoor or washdown suitability is not established here.
