As a global leader in standard power supply solutions, MEAN WELL is committed to delivering efficient and intelligent KNX building automation control solutions. Following the successful launches of the LCM-KN series (constant current drivers) and PWM-KN series (constant voltage drivers), MEAN WELL further expands its KNX LED driver product line with the introduction of the XLC-25/40/60KN series. This series not only inherits the core advantages of MEAN WELL's existing KNX LED drivers but also features optimized designs for enhanced intelligence and compactness. Compliant with the EN61347-2-13 standard for emergency lighting (EL), these drivers seamlessly integrate into KNX systems without requiring additional gateways.


Key Features
  • Compact Design
  • Constant Current Output
  • Class II Design
  • Emergency Lighting Support
  • Ultra-Low Dimming to 0.5%
  • Direct KNX Communication

Advanced KNX Functions and Application Scenarios

     The XLC-25/40/60KN series not only includes MEAN WELL's existing KNX LED driver functions but also introduces advanced intelligent control features, making it more efficient and flexible for smart building lighting applications.


1. Auto-Dimming Over Time   

     This feature allows the LED driver to automatically adjust brightness based on the time provided by an external KNX Timer (up to 10 steps per day) without requiring additional control commands. Users can choose to manually intervene by sending commands during the automatic dimming process to determine whether the system should respond or not, which provides greater flexibility.
 


 

2. Energy Consumption Feedback

     This feature records the output power and efficiency of the LED driver, estimating energy consumption over periods ranging from 10 minutes to 1 week. The data is then fed back to KNX system management, helping users optimize energy budgets.
 

 
 

3. Temperature Function

     Through temperature monitoring, the system can provide real-time feedback on the power detection point temperature and set over-temperature warnings to adjust output in advance.
 


 

4. Lamp Characteristic Curve Correction

     Corrects inconsistencies in brightness output for non-linear LED fixtures, ensuring that actual brightness aligns with dimming commands and avoiding uneven lighting.
