The DALI SDL-13 controller is designed to control RGB LEDs through the DALI interface bus. The terminal elements connected to the controllers can be LEDIX low voltage fittings, tapes and diode modules. The controller converts DALI protocol messages to an PWM output signal controlling the lighting level and the color of the RGB LEDs. The control bus consists of two lines that can be run together with power lines. Small dimensions allow easy installation in a box. 60. The DALI controller enables easy implementation of LED products in complex lighting systems whose operation is based on the DALI interface. SDL-11 can also act as a controller in autonomous LED lighting systems.
