SR-2309PRO7 DALI 4-channel LED dimmer CC 12-48VDC 700mA DT8

Sunricher SR-2309PRO7 is a professional multifunctional 4-channel DALI-2 LED controller with constant output current (CC), designed for dimming and controlling LED modules with the required current 700 mA. It supports both DALI DT8 and DT6 mode, which 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 provides four constant current output channels 700 mA per channel. The maximum output power of one channel reaches 33.6 W, while the total maximum output power is 134.4 W at 48 V DC. The device requires an external DC power supply.

The controller offers six configurable operating modes:

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

• DT8 RGBWAF – joint control of the intensity and colors of multi-colored LED lighting.

• DT8 XY – color management through XY color coordinates.

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

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

• DT6 – dimming of single-color LED lighting.

Depending on the selected mode, the device uses one or two DALI addresses. Operating mode and addressing can be set using integrated buttons and a digital display.

The controller 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, it is also possible to change the color temperature or color of the light.

The SR-2309PRO7 is suitable for integration into intelligent KNX electrical installations via a compatible KNX–DALI gateway, as well as into separate DALI lighting systems.
