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. 10. 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-90-42 for 42V LED signage or display lighting?

It can be used for 42V LED signage or display lighting when the load matches the 42V output and stays within 90.3W total. This is a constant voltage + constant current driver with a 25.2-42V constant current region, so the connected lighting load needs to fall inside that range.

Is the LPF-90-42 a fit for 42V linear lighting fixtures?

Yes, it is suited to 42V linear lighting fixtures that need up to 2.15A and no more than 90.3W. The fixture should be designed to operate within the driver's 25.2-42V constant current region.

Can the LPF-90-42 be used for outdoor decorative or facade lighting?

Yes, this model is often considered for outdoor decorative or facade lighting because it is IP67 rated and operates at a case temperature (Tcase) of -40°C to +70°C, with load derating at higher temperatures. The lighting load still needs to match the 42V output class and remain within 90.3W.

How do I estimate LED strip length for the LPF-90-42?

Use the driver's maximum power: 90.3W. The length calculation is 90.3W divided by your strip's watts per meter, so maximum length = 90.3W / rated W per meter. Check your strip rated power per meter before sizing the run.

Is the LPF-90-42 suitable for wet or exposed environments?

The LPF-90-42 carries an IP67 rating and operates at a case temperature (Tcase) of -40°C to +70°C, with load derating at higher temperatures. That makes it appropriate for wet or exposed locations when those environmental limits fit the project.

What are the main output differences between LPF-90-42 and the other LPF-90 models?

The LPF-90 family includes 15V at 75W and 5A, 20V at 90W and 4.5A, 24V at 90W and 3.75A, 30V at 90W and 3A, 36V at 90W and 2.5A, 42V at 90.3W and 2.15A, 48V at 90.24W and 1.88A, and 54V at 90.18W and 1.67A. All models share the 90-305VAC input range and the same 161*61*36mm case.
