Information about the MEAN WELL LCM-40KN
The MEAN WELL LCM-40KN is a high-performance 40W LED driver designed for direct implementation into KNX building automation environments. By featuring a built-in KNX interface, it eliminates the requirement for complex KNX-DALI gateways, streamlining the installation process and lowering overall system costs. A standout feature is its multiple-stage constant current output, allowing users to select current levels between 350mA and 1050mA via integrated DIP switches. This flicker-free design guarantees superior light quality, making it ideal for professional office spaces and architectural lighting projects.
Beyond standard lighting control, the LCM-40KN supports advanced digital functions such as Constant Light Output (CLO), operating hours monitoring, and power consumption feedback directly to the KNX bus. The unit also includes a useful 12V auxiliary DC output for powering small external devices like sensors and offers the capability to synchronize up to ten drivers for perfectly matched lighting zones. With its slim Class II plastic housing and compliance for emergency lighting applications, this driver provides a reliable and future-proof solution for intelligent building projects, maintaining stable operation even at case temperatures up to 90°C.
