LCM-15 is a 25W LED power supply unit that supplies multiple current levels, 350mA/ 500mA/ 600mA/ 700mA/ 900mA/ 1050mA. The current levels are able to be easily switched by adjusting the built-in DIP switch. LCM-15 also provides the dimming function that is controlled by external 0-10VDC or PWM signal or resistance. Moreover, the synchronization design allows the dimming for up to 10 units of LCM-25 to be controlled simultaneously.
