How to use
To use the MEAN WELL LCM-40KN, first select the appropriate output current using the built-in DIP switches to match the requirements of your LED load. Connect the AC input wires to the designated terminals, ensuring the power supply is disconnected during installation. Connect the LED modules to the output terminals, observing correct polarity. If using the KNX or push dimming features, connect the control wires to the respective terminals according to the wiring diagram. Once all connections are secure, verify the setup before applying power to the system.
What to consider before purchase
Ensure the total power consumption of your LED load does not exceed 40 W.
Verify that your LED modules are compatible with constant current operation.
Check if your existing control system supports the KNX protocol.
Confirm that the installation environment meets the indoor usage requirements.
Usage recommendations
Always ensure that the output current setting matches the specifications of your LED modules to prevent damage. Perform a final check of all wiring connections before switching on the power supply to ensure safety and optimal performance.
