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-25D-36 with a 36V constant-current LED fixture?

Yes, if the fixture is specified for constant-current operation at 0.7A and works within the 19.8–36V constant-current range. The driver delivers up to 25.2W at 36V, so the connected load must stay within that limit.

Is this a good fit for weather-exposed sign lighting?

It can be used for weather-exposed sign lighting when the sign's LED module needs 0.7A constant current and operates from 19.8V to 36V. The IP67 rating suits wet environments, and the maximum output is 25.2W.

Can this driver power a dimmable linear lighting run?

Yes, for a linear lighting product that is designed for constant current at 0.7A and falls inside the 19.8–36V range. This unit includes built-in 3 in 1 dimming and provides up to 25.2W.

How do I estimate LED strip length for the LPF-25D-36?

Size it by current and voltage rather than watts per meter: the driver supplies a constant 0.7A within a 19.8–36V constant current region, up to 25.2W total. The strip must be a constant-current load rated for 0.7A with an operating voltage within 19.8–36V; a constant-voltage 36V strip is not a match.

Is the LPF-25D-36 suitable for outdoor or washdown areas?

Its IP67 rating supports outdoor and wet environments; the sheet does not give a rating for washdown jets. It is specified for a case temperature (Tcase) of -35°C to +70°C with load derating at higher temperatures, so the case temperature needs to remain within that range.
