Test conditions and notes12
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Please refer to "DRIVING METHODS OF LED MODULE".
  3. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  4. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
  7. 7. The driver 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)
  8. 8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
  9. 9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
  10. 10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  11. 11. 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).
  12. 12. 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

FAQ

Can I use the LPF-25-20 for a 20V LED strip or linear light run?

Yes, if the strip or fixture is designed for 20V operation and the total load stays within 25W. This driver provides 20V at 1.25A, so it fits smaller 20V lighting sections rather than larger runs. Check the light’s rated voltage and total power before selecting it.

Is the LPF-25-20 suitable for compact illuminated signage?

It can be a fit for compact 20V sign lighting when the load does not exceed 25W. The IP67 waterproof rating is useful for sign installations exposed to dust or water. Confirm the sign lighting modules are rated for 20V and stay within 1.25A.

Can this model be used for small 20V accent or cove lighting?

Yes, for small 20V accent or cove lighting sections that stay within the 25W output limit. Its 20V output and 1.25A current make it appropriate for lower-power applications with matching electrical requirements. Verify the fixture or strip specification before use.

Is the LPF-25-20 appropriate for outdoor or damp environments?

Yes, the driver is rated IP67 waterproof, so it is built for wet and dusty conditions. Its working case temperature (Tcase) range is -35°C to +70°C, which supports many indoor and outdoor locations. The connected lighting product still needs its own environmental rating.

How many meters of 20V LED strip can the LPF-25-20 support?

Estimate the run by dividing the driver’s 25W maximum by the strip’s watts per meter. Length = 25W divided by rated W/m, so a 5W/m strip would be about 5 meters. Check your strip rated power per meter before sizing the final run.
