Test conditions and notes14

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. 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.
6. Flicker is measured at full load with the light source provided by MEAN WELL.
7. To fulfill requirement of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
8. 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)
9. The ambient temperature de-rating of 3.5℃/1000m with fanless models and 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
10. 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.
11. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
12. Products sourced from the Americas regions may not have the CCC/PSE/BIS/KC logo. Please contact your MEAN WELL sales for more information.
13. For more information, please contact with MEAN WELL sales.
14. Products sourced from the China regions may not have the BIS logo, please contact your MEAN WELL sales for more information.

The Mean Well XLN-40-24 is a 40.8 W constant-voltage LED driver with a 24 V output. Its rated output current is 1.7 A, making it suitable for compatible 24 V LED loads within that power range.

What type of LED applications is the XLN-40-24 intended for?

The XLN-40-24 is intended for 24 V constant-voltage LED lighting applications. Its 40.8 W rating makes it a fit for smaller LED driver requirements where a compact AC-DC LED power supply is needed.

Can the XLN-40-24 be used in demanding environments?

This model is fully encapsulated and rated IP67, which supports use in environments where protection from dust and water ingress is important. Its listed operating temperature range is -25 °C to 90 °C.

Is the Mean Well XLN-40-24 dimmable?

The XLN-40-24 is a constant-voltage model with a fixed 24 V output and does not include dimming functionality. Dimming features are available on other variants in the XLN-40 series, such as the B and DA2 types.

Is the XLN-40-24 compatible with 12 V LED products?

This specific model has a 24 V output and should be matched with compatible 24 V constant-voltage LED products. It is not listed here as a 12 V output model.

What warranty does the XLN-40-24 include?

The Mean Well XLN-40-24 is listed with a 5-year warranty. That warranty period is a useful consideration for B2B buyers comparing LED drivers for long-term lighting projects.
