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-40D-30 for a 30V LED strip lighting project?

Yes, if the strip or fixture is a constant-current LED load within the 18-30V CC region, 1.34A and 40.2W total. The built-in 3 in 1 dimming also supports applications that need adjustable brightness.

Is this driver suitable for 30V backlit signage?

It can be a fit for 30V constant-current signage lighting products within the 18-30V CC region, 1.34A and the driver's 40.2W output capacity. Its IP67 waterproof construction is also useful for signage exposed to outdoor or wet conditions.

Can the LPF-40D-30 be used for dimmable 30V linear architectural lighting?

Yes, for 30V linear lighting systems that operate within 18-30V CC and do not exceed 1.34A. The dimmable design makes it appropriate for architectural lighting where output control matters.

How much 30V LED strip can this driver handle?

This is a constant-current driver, so size by current and voltage: the strip must be designed for 1.34A constant current with a voltage within 18-30V. Check your strip's rated current and voltage, and keep the total load within 40.2W.

Is the LPF-40D-30 suitable for outdoor lighting applications?

The IP67 waterproof rating makes it suitable for outdoor and wet-location lighting assemblies where that level of sealing is needed. Its case temperature (Tcase) range is -40°C to +80°C, with load derating at higher temperatures.
