Test conditions and notes12

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
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. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. 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. 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. 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. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
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. 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-24 for 24V LED strip cove lighting?

Yes, if the strip is a constant-current LED load rated for 1.67A with a voltage within the 14.4-24V CC region (max. 40.08W). The built-in 3 in 1 dimming is useful for cove lighting where adjustable light level is needed.

Is this driver suitable for 24V sign lighting or light boxes?

It can be used for constant-current sign lighting products within the 14.4-24V CC region, 1.67A and 40.08W. Its IP67 rating also makes it suitable where sign lighting equipment may be exposed to moisture.

Can the LPF-40D-24 run 24V retail shelf or display lighting?

Yes, for constant-current LED strip or linear lighting loads within 1.67A and the 40.08W output limit. The 14.4-24V CC range and dimming support make it a practical option for controlled retail display lighting.

What is the maximum 24V LED strip length this power supply can support?

This is a constant-current driver, so size the load by current and voltage rather than length: the LED strip or module must be designed for 1.67A constant current with a voltage within 14.4-24V, keeping the load within 40.08W. Check your strip's rated current and voltage.

Is the LPF-40D-24 okay for wet or exposed conditions?

Yes, its IP67 waterproof rating indicates suitability for wet and outdoor conditions when that enclosure level is required. It is rated for a case temperature (Tcase) of -40°C to +80°C, with load derating at higher temperatures.
