The DT8 RGBW DALI MCU features a built-in 100mA DALI power supply capable of powering up to 50 DALI ECGs and supports DALI DT8 RGBW devices with color type RGBWAF, allowing independent control of the W channel separate from the RGB channels.
It can operate on AC mains or be powered by the DALI bus, and supports broadcast control of up to 100 DALI ECGs on a single DALI line when using four MCUs (two powered by AC mains, two by DALI bus). It also allows setting and deletion of a minimum dimming level.
