LCM-40TW – Dual channel dimmable LED driver from MEAN WELL
LED lighting is being improved based on the technical capabilities of its components. So, in accordance with the possibilities, multi–color illumination systems or lighting systems with different color temperatures appear - more comfortable for working or moving at different times of the day. As an example, we can cite modern metro trains with a colder light of the lighting system in the morning and a warmer one in the evening. The two-channel LCM-40TW LED driver from MEAN WELL is an ideal power source for lighting systems of this type.
Appearance of the LCM-40TW LED driverThe LCM-40TW driver is designed for use in LED lighting systems with different operating algorithms with the ability to connect and control two LED channels, including brightness control, via the DALI or PUSH Dim protocol, which significantly expands the options for using the power supply from household to office and specialized lighting:
Connecting the PUSH Dim input or the DALI interfaceThe main technical characteristics are presented in the table:

The LCM-40TW LED driver has protection against overload, short circuit, overheating. The driver is cooled by natural convection, without the use of a fan. Operating ambient temperature: -30...+45°C. Warranty period: 5 years.
The level of output current and used channels of the DALI device type 6 (DT6) and device type 8 (DT8) types is set using the built-in DIP switches:
Setting the output current and the channels usedDepending on the set settings and the connection scheme, it is possible to work in single-channel and dual-channel operation mode (DT6), as well as in the color temperature selection mode (DT8):
Operating modes and connection of LED to LCM-40 TWThe LCM-40TW LED dimmable driver is designed to create lighting systems with adjustable color temperature, decorative and auxiliary illumination, lighting systems controlled by the DALI protocol.
