JUNG KNX DALI-2 Actuator Colour 4-fold, DIN Rail, 4 TE, Secure (300041SDA2R)

This KNX DALI-2 actuator from JUNG stands out with its four independent DALI-2 channels, each capable of controlling up to 64 DALI devices, making it a flexible solution for professional lighting control. With integrated DALI power supplies per channel and support for KNX Secure, it ensures reliable and protected communication in building automation systems.

Highlights

• Four DALI-2 channels for individual control of lighting groups
• Supports switching, dimming, and colour control (RGB, RGBW, tunable white, XY colour)
• Integrated DALI power supply per channel, no external supply needed
• KNX Secure for encrypted communication
• Compact DIN rail mounting, only 4 TE wide

In daily use

Configured via ETS, the actuator provides precise control over DALI luminaires, including scene management and diagnostic functions. It operates directly from the KNX bus voltage (21-30 V DC), simplifying installation in distribution boards.
