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-54 for a 54V dimmable LED lighting load?

Yes, this is a 54V constant current LED driver with built-in 3 in 1 dimming for lighting loads operating within its 32.4-54V constant current range. The connected load must stay within 90.18W and be rated for the 1.67A output current.

Is the LPF-90D-54 a good fit for outdoor signage or wet-area lighting?

Yes, the driver is rated IP67 waterproof, so it is intended for outdoor and wet-location LED lighting use. It is rated for a working case temperature (Tcase) of -40°C to +70°C.

Can this 54V model be used for long-run linear lighting or sign lighting systems?

It can be used where the lighting load is designed for constant current operation and matches the 32.4-54V range, 1.67A output current, and 90.18W maximum power. That makes it more appropriate for matched 54V-class lighting loads than lower-voltage products.

How much 54V LED strip can the LPF-90D-54 support?

Use the power limit for the calculation: maximum strip length equals 90.18W divided by your strip's rated watts per meter. Check your strip rated power per meter, and also confirm the strip is designed for constant current operation because this is a constant current mode LED driver.

How does the LPF-90D-54 compare with the other LPF-90D versions?

The dimmable LPF-90D range includes LPF-90D-15 at 75W, 15V, 5A; LPF-90D-20 at 90W, 20V, 4.5A; 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. This version is the highest-voltage option in that dimmable 90W group.
