Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Output hiccups under no-load condition.
3. Please refer to “DRIVER METHODS OF LED MODULE”.
4. De-rating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. Efficiency is measured at 800mA/50V output set by ETS database.
7. Standby power consumption is measured at 230VAC.
8. Flicker is measured at full load with the light source provided by MEAN WELL.
9. 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)
10. For XLC-S series: RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations. For XLC(except -S) series: RCM is on a voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1
11. 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).
12. 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.

FAQ

Can I use the XLC-40-H-KN to drive LED downlights in a KNX smart building system?

Yes, the XLC-40-H-KN is specifically designed for KNX system integration, allowing it to receive dimming commands from a KNX bus controller. It delivers 40W constant current with a default 600mA output and can dim down to a minimum of 0.5%, making it appropriate for addressable LED downlight control in KNX-based commercial or residential lighting systems.

Is the XLC-40-H-KN a good fit for LED signage modules controlled from a KNX panel?

The XLC-40-H-KN can power LED signage modules whose forward voltage falls within the 9–54V CC output range, as long as total load stays within 40W. Combined with KNX control, it enables centrally scheduled brightness changes for illuminated signage without a separate dimming controller.

Can the XLC-40-H-KN power LED arrays in museum or retail accent lighting tied to a KNX scene controller?

The XLC-40-H-KN suits KNX-controlled accent or display lighting where scene-based dimming is needed. Its 40W constant current output at a default 600mA supports small LED arrays with compatible Vf in the 9–54V range. The 0.5% minimum dimming level provides smooth fade capability for scene transitions.

How is the output current set on the XLC-40-H-KN?

The XLC-40-H-KN output current is set via the ETS database, allowing selection between 600mA and 1400mA. This digital configuration is made through the KNX interface, making it suitable for installations where current is set during commissioning via software. Unlike models with fixed current, changes require access to the ETS programming tool.

Does the XLC-40-H-KN have a strain-relief fitting for the output cable?

No, the XLC-40-H-KN does not include a strain-relief fitting. It uses a compact 107.0 × 40.0 × 32.0 mm housing without the strain-relief attachment. The XLC-40-H-KNS is the corresponding variant that adds a strain-relief cable fitting for installations where mechanical cable security is required.

Can the XLC-40-H-KN be installed inside a luminaire or enclosed ceiling fitting?

The XLC-40-H-KN is rated for built-in use, meaning it is designed to be housed inside a luminaire or enclosure rather than mounted externally. Its operating temperature range of -25°C to +90°C accommodates typical thermal conditions inside enclosed ceiling fixtures. It does not carry an IP rating for moisture exposure.
