Skydance 4 channel constant voltage DALI LED dimmer

Skydance 4 Channel Constant Voltage DALI LED Dimmer (SK-DA4) is a professional 4-channel independent dimmer by Skydance, designed for the advanced control of LED strips and constant voltage lighting systems via the DALI protocol. With an input compatible with 12 V, 24 V and 48 V DC, the device delivers a manageable output of up to 4×60 W at 12 V, 4×120 W at 24 V, 4×108 W at 36 V and 4×144 W at 48 V, making it suitable for installations of varying scale and complexity. Its compact dimensions — 175 × 45 × 27 mm — make installation straightforward even in confined technical spaces.

The unit is DALI-2 certified in accordance with standard protocol IEC 62386-101, 102 and 207, ensuring full compatibility with DALI systems from other international manufacturers. Each channel features an independent DALI address, automatically assigned by the DALI master, enabling granular and flexible control of every individual circuit. The PWM digital dimming follows the DALI standard logarithmic dimming curve, delivering a light intensity adjustment that is perceptually smooth and natural to the human eye. The system also incorporates overload and short circuit protection with automatic reset, ensuring reliable and uninterrupted operation even in demanding environments. Compatibility with international electrical standards — EU, AUD, USA, UK and JAP — and an operating temperature range of -30° to +55°C make it well suited to a wide variety of installation contexts. These features make the SK-DA4 a benchmark technical solution for system integrators, professional installers and lighting designers working on residential, commercial or contract projects.
