Dimming The extra dimension of LED light Where are we today The tendencies Koen Vangorp Director Sales & Marketing Telerex ORGANISATION LOGISTICS FINANCE PORTAL QUALITY MARKETS 8 LAKES GROUP Dimming The extra dimension of LED light Practical examples MW LCM Combined multiple dimming Output current by DIP switch NTC current correction The major difference between LCM-60 and LCM-60DA is the control board which converts the DALI signal into PWM dimming signal. Other differences are the Push dimming functions and connectors.
