SkyDance DT-B Triac DALI Dimmer Controller 100-240VAC 150–360W (DT4)
The SkyDance DT-B is a professional single-channel DALI AC TRIAC dimmer designed for brightness control and switching of dimmable LED fixtures, traditional incandescent bulbs, and high-voltage halogen lamps. The device uses a single DALI address and operates in the DT4 standard, ideal for commercial and architectural installations.
The dimmer is DALI-2 certified and fully compliant with the IEC 62386 standard, ensuring reliable interoperability with third-party DALI systems. Addressing is performed automatically by the DALI controller (DALI master), simplifying system configuration.
The DT-B supports both leading-edge and trailing-edge dimming – the mode can be selected to suit the characteristics of the connected load. The ability to set a minimum brightness level helps prevent flickering at low brightness levels. Additionally, the device allows for control via an external monostable switch (on/off + 0–100% dimming).
