Test conditions and notes12
- 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 0.1uf & 47uf 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. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 6. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 7. Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immerse in the water over 30 minute.
- 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).
- 9. Products sourced from the Americas regions may not have the TUV/BIS/CCC logo. Please contact your MEAN WELL sales for more information.
- 10. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
- 11. This product is not intended for LED lighting luminaire applications in the EU and China.(In the EU and China the LPF/NPF/XLG/XLC/XLN series are recommended.)
- 12. Products sourced from the China regions may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ
What LED lighting applications is the LPV-20-12 suitable for?
The LPV-20-12 outputs 12V DC at up to 1.67A (20W total), making it practical for powering short runs of 12V LED strip, small under-cabinet lighting, and compact illuminated signage where total load stays at or below 20W. It is not suited to large-area installations that require more than 20W.
How many meters of 12V LED strip can the LPV-20-12 power?
The driver supplies a maximum of 20W at 12V. Divide 20W by your strip's rated power per meter to find the limit — for example, at 4.8W/m the result is approximately 4.2 m. Always verify your strip's rated power per meter and keep a safety margin to avoid overloading the driver.
Is the LPV-20-12 suitable for outdoor or damp locations?
Yes. The IP67 rating means the unit is dust-tight and protected against temporary immersion in water (avoid more than 30 minutes), so it can be used in outdoor sign boxes, under eaves, or in garden lighting fixtures out of direct sunlight. Its operating temperature range of -30°C to +70°C (see derating curve) supports cold-weather outdoor installations.
Will the LPV-20-12 work on 110V or 120V mains?
Yes. The input range is 90–264VAC, which covers North American 120V, European 230V, and all voltages in between. No input switching or configuration is required when moving between supply voltages in that range.
How does the LPV-20-12 compare to the LPV-35-12 for a small 12V LED project?
The LPV-20-12 supplies 12V at up to 1.67A, or 20W. If your 12V LED load draws up to 20W, the LPV-20-12 is adequate; for larger 12V loads you would need a higher-power model such as the LPV-35-12 — check its own datasheet for its current and power ratings.
