4 Channels DALI DT8 Dimmer with Built-in Master Function

The SR-2309FA-OLED is a versatile, professional-grade 4-channel constant-voltage dimming controller tailored for advanced LED installations.

Operating at 12–36 V DC, it delivers up to 4 × 5 A outputs, supporting a total load capacity of approximately 240-720 W depending on system voltage. 

What sets it apart is the built-in DALI-2 master function and a crisp OLED display for on-site configuration without needing extra tools. 

It supports full DT8 colour control — including tunable white (Tc), XY colour coordinates, RGBWA and mixed colour types — all managed through one device, making it ideal for modern architectural, studio or high-end LED setups. 

With its ability to set fade times, scene recall, adjustable PWM frequency (250Hz-30kHz) for flicker-free dimming, and digital address and group management via the display, the SR-2309FA-OLED merges flexibility, precision and ease of commissioning. 

Whether integrated into a smart lighting network or used stand-alone, this unit brings professional control and streamlined installation into one compact package.
