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 75℃ 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-40-15 for 15V LED lighting products?

Yes, if the lighting product is designed for 15V input and the total load does not exceed 40.08W. This model provides 15V output at up to 2.67A, so both the voltage match and the total wattage matter.

Is the LPF-40-15 suitable for 15V illuminated signage?

It can be used for 15V illuminated signage where the connected load stays within 40.08W. The IP67 Waterproof rating also makes it appropriate for sign applications that may be exposed to rain.

Can this model be used for outdoor 15V decorative lighting?

It is suitable for outdoor 15V decorative lighting loads within its 40.08W rating. The driver is IP67 rated and specified for a case temperature (Tcase) of -40°C to +80°C, so the unit itself is built for harsh environments.

How do I estimate LED strip length for the LPF-40-15?

Use the strip's rated watts per meter and divide 40.08W by that number to estimate the maximum length. Also make sure the strip is a 15V strip, because this driver's output is 15V at up to 2.67A.

Can the LPF-40-15 be used in wet or exposed locations?

Yes, its IP67 Waterproof rating indicates suitability for wet and outdoor conditions. It is also specified for a case temperature (Tcase) of -40°C to +80°C, which helps in environments with wide temperature swings.

What is the difference between the LPF-40-15 and the other 40W LPF voltage options?

The LPF-40 family includes LPF-40-12 at 40.08W, 12V, 3.34A; LPF-40-15 at 40.08W, 15V, 2.67A; LPF-40-20 at 40W, 20V, 2A; LPF-40-24 at 40.08W, 24V, 1.67A; LPF-40-30 at 40.2W, 30V, 1.34A; LPF-40-36 at 40.32W, 36V, 1.12A; LPF-40-42 at 40.32W, 42V, 0.96A; LPF-40-48 at 40.32W, 48V, 0.84A; and LPF-40-54 at 41.04W, 54V, 0.76A. They are similar in power class, but the voltage and current outputs change by model.
