Mean Well KNX LED Driver LCM-40KN Series Data Sheet Download
Description
LCM-40KN series is a 40W AC/DC constant current mode output LED driver featuring the multiple levels selectable by dip switch and the KNX interface to avoid using the complicated KNX-DALI gateway. LCM-40KN operates from 180~ 295VAC and offers different current levels ranging between 350mA and 1050mA. Thanks to the high efficiency up to 90%, with the fanless design, the entire series is able to operate for -30℃ ~+90℃ case temperature under free air convection. In addition, LCM-40KN is equipped with push dimming and synchronization so as to provide the optimal design flexibility for LED lighting system.
