Product information

Description

The MEAN WELL LCM-40KN is a high-performance constant current LED driver designed to provide reliable power for various lighting systems. With a maximum output power of 40 W and a versatile multi-stage output current selection, this driver ensures optimal performance for different LED configurations. It is engineered to operate within an input voltage range of 180 to 295 V AC, making it suitable for standard electrical grids. The unit features integrated KNX and push dimming capabilities, allowing for precise control over lighting intensity in smart building environments.

Advantages

This LED driver stands out due to its flexible output current settings, which can be adjusted to 0.35 A, 0.5 A, 0.6 A, 0.7 A, 0.9 A, or 1.05 A, providing compatibility with a wide range of LED modules. The inclusion of KNX interface support allows for seamless integration into automated building control systems, enhancing energy efficiency and user convenience. Its compact and slim design ensures that it can be easily installed in tight spaces, such as ceiling voids or electrical enclosures, without compromising on thermal management or operational stability.

Suitable for

  • Smart home and building lighting automation
  • Commercial LED lighting installations
  • Dimmable LED panel and downlight systems
  • Architectural lighting projects requiring KNX control

This driver may not be suitable for applications requiring constant voltage output, as it is specifically designed for constant current operation. Additionally, it is not intended for outdoor environments without appropriate protective housing, as it is designed for indoor use.

Key specifications

  • Output power: 40 W
  • Input voltage range: 180-295 V AC
  • Output current options: 0.35 A, 0.5 A, 0.6 A, 0.7 A, 0.9 A, 1.05 A
  • Dimming interfaces: KNX and push dimming
  • Dimensions: 81.5 mm x 123.5 mm x 23 mm

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.
