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-48 for a 48V LED lighting project that needs dimming?

Yes, this model is a 48V constant current LED driver with built-in 3 in 1 dimming, so it suits dimmable 48V lighting loads that operate within its 28.8-48V constant current range. Keep the load within 90.24W and rated for the 1.88A output current.

Is the LPF-90D-48 suitable for outdoor illuminated signage or wet-location lighting?

Yes, it has an IP67 waterproof rating, so it is intended for outdoor or wet-location LED lighting applications. Its working case temperature (Tcase) range is -40°C to +70°C, with derating per the load vs temperature curve, which supports demanding environmental conditions.

Can this driver be used for 48V linear lighting or architectural lighting runs?

It can be used for 48V linear lighting loads that are designed for constant current operation at 1.88A, stay within 90.24W, and operate in the 28.8-48V constant current range. The built-in 3 in 1 dimming also makes it suitable where adjustable light output is required.

Can I use the LPF-90D-48 with 48V LED strips for signage or cove lighting?

Only if the 48V strip is designed to work with a constant current driver, because this is a constant current mode LED driver. Power capacity is 90.24W, so maximum strip length is calculated as 90.24W divided by your strip's rated watts per meter; check your strip rated power per meter and confirm constant current compatibility.

What is the difference between the LPF-90D voltage options?

The dimmable LPF-90D siblings are 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. The main differences are output voltage, current, and slight wattage variation by model.
