SR-2309PRO3 DALI 4-channel LED dimmer CC 12-48VDC 350mA DT8

Sunricher SR-2309PRO3 is a professional multifunctional 4-channel DALI LED controller with constant output current (CC), designed for dimming and controlling LED modules requiring power supply 350 mA. It supports DALI DT6 and DT8, thanks to which it enables regulation of lighting intensity, white light chromaticity temperature and color parameters of compatible LED modules.

The controller works with with an input voltage of 12–48 V DC and has four output channels with constant current 350 mA per channel. The maximum power of one channel is 16.8 W, while the total maximum output power reaches 67.2 W. The device requires an external DC power supply.

The controller offers six configurable operating modes, which allow the control to be adapted to a specific type of LED lighting:

• DT8 Tc – regulation of intensity and color temperature of white light (Tunable White).

• DT8 RGBWAF – joint control of RGBW lighting intensity and colors.

• DT8 XY – color management through XY color coordinates.

• DT8 2 × Tc – independent control of two groups of Tunable White lighting through two DALI addresses.

• DT8 XY + DT6 – combined control of colored RGB lighting and a separate white channel via two DALI addresses.

• DT6 – dimming of single-color LED lighting.

Depending on the selected mode, the controller uses one or two DALI addresses. The operating mode and DALI address can be set using integrated buttons and a digital display.

The device also supports Push DIM, which allows the lighting to be controlled by an external button without the need for a DALI control unit. In the respective modes, in addition to dimming, the color temperature or color of the light can also be adjusted.

The SR-2309PRO3 is suitable for integration into intelligent KNX electrical installations via a compatible KNX–DALI gateway, as well as into separate DALI systems.
