MEAN WELL LCM-40KN 40W KNX Constant Current LED Driver (350-1050mA, DIP Switch)

The LCM-40KN stands out by integrating KNX bus control directly into a constant-current LED driver, enabling smart lighting control without an external KNX actuator. With six selectable output currents from 350mA to 1050mA via DIP switch, it adapts to a wide range of LED modules while maintaining a compact plastic housing for indoor installations.

Highlights

• KNX interface for direct integration into building automation systems
• Selectable output current: 350mA, 500mA, 600mA, 700mA, 900mA, 1050mA
• Wide output voltage range up to 114V DC accommodates various LED configurations
• High efficiency up to 88% and power factor >0.9 at 230VAC
• Push dimming support for manual control

In daily use

Set the desired current with the DIP switch, connect the KNX bus, and the driver is ready for intelligent lighting scenes. The IP20 plastic housing is suitable for dry indoor locations, and standby power consumption below 0.5W in KNX mode keeps energy use low when lights are off.
