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-90D-24 for a 24V LED strip installation?

Yes, if the strip is designed to be driven by a constant current source and the full run stays within 90W. This constant current driver delivers 3.75A across a 14.4-24V constant current region, so it is suitable for larger 24V strip lighting loads, but check your strip rated power per meter before sizing.

Is the LPF-90D-24 a good fit for 24V sign lighting?

It can be used for 24V LED signage and illuminated display projects where the load does not exceed 90W. The IP67 waterproof rating is useful when the sign or enclosure is exposed to weather or wet conditions.

Can this model run 24V linear or accent lighting in indoor and outdoor spaces?

Yes, for 24V lighting products designed for constant current operation within the 14.4-24V region at 3.75A. Its IP67 housing and Tcase -40°C to +70°C working range (derating per the load vs temperature curve) make it suitable for both sheltered indoor use and harsher outdoor conditions.

How do I estimate the maximum 24V LED strip length for the LPF-90D-24?

Use the formula: maximum strip length = 90W divided by the strip wattage per meter. This driver is limited to 90W total output at 24V and 3.75A, so check your strip rated power per meter before deciding the run length.

Can the LPF-90D-24 be used outdoors or in wet areas?

Yes. It is rated IP67 waterproof with a working case temperature (Tcase) of -40°C to +70°C, so it is built for wet, dusty, and outdoor environments as well as indoor applications.

What are the differences between the LPF-90D-24 and the other LPF-90D versions?

The LPF-90D dimmable siblings are LPF-90D-15 at 75W, 15V, 5A; LPF-90D-20 at 90W, 20V, 4.5A; LPF-90D-30 at 90W, 30V, 3A; LPF-90D-36 at 90W, 36V, 2.5A; LPF-90D-42 at 90.3W, 42V, 2.15A; LPF-90D-48 at 90.24W, 48V, 1.88A; and LPF-90D-54 at 90.18W, 54V, 1.67A. The LPF-90D-24 itself is the 24V, 3.75A, 90W member of that series.
