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-20 for a 20V LED strip lighting run?

Yes, if the strip system is designed for constant current drive and the total load stays within 90W. This model delivers 4.5A across a 12-20V constant current region, so it suits longer or higher-density 20V strip runs than lower-power models, but check your strip rated power per meter before sizing.

Is the LPF-90D-20 suitable for 20V illuminated signage?

It can be a fit for 20V LED signage modules or sign-lighting assemblies that stay within 90W total load. The IP67 waterproof rating also makes it suitable for sign projects exposed to wet conditions.

Can this driver power a 20V outdoor architectural lighting fixture?

Yes, for 20V lighting products designed for constant current operation within the 12-20V region at 4.5A and up to 90W. Its IP67 waterproof housing and Tcase -40°C to +70°C working range (derating per the load vs temperature curve) make it appropriate for demanding indoor or outdoor environments.

How much 20V LED strip can the LPF-90D-20 run?

Use the power formula: maximum strip length = 90W divided by your strip wattage per meter. For example, the driver's limit is 90W total at 20V and 4.5A, so you must check your strip rated power per meter before calculating the allowable length.

Is the LPF-90D-20 okay for wet or outdoor locations?

Yes. It has an IP67 waterproof rating and a working case temperature (Tcase) range of -40°C to +70°C, so it is intended for wet and outdoor conditions as well as indoor use.

How does the LPF-90D-20 compare with other LPF-90D models?

Within the LPF-90D dimmable range, sibling outputs are LPF-90D-15 at 75W, 15V, 5A; LPF-90D-24 at 90W, 24V, 3.75A; 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-20 version is the 20V, 4.5A, 90W option in that dimmable group.
