SkyDance DA4-D – 4-Channel DALI CV Dimmer 12-48V DC (DIN Rail, DT6 / DT8)
The SkyDance DA4-D is a professional 4-channel Constant Voltage LED driver designed for DALI/DALI-2 systems. The device supports up to 5A per channel and works with 12-48V DC systems, offering high output power and complete flexibility in lighting configuration.
The dimmer supports DT6 and DT8 modes, including CCT, RGB, and RGBW. In DT6 mode, it can operate with up to 1-4 DALI addresses, with each channel operating independently.

A clear digital display allows for manual assignment of DALI addresses and quick verification of the device configuration.
The DA4-D also supports automatic addressing via the DALI master.
Digital PWM with a logarithmic DALI dimming curve and selectable PWM frequencies from 1kHz to 16kHz ensures smooth and stable regulation.
DIN rail mounting makes the DA4-D ideal for switchboards and professional lighting control systems.
