SR-2309PRO DALI 4-channel LED dimmer CV 12-48VDC 5A DT8

Sunricher SR-2309PRO is a professional multifunctional 4-channel DALI-2 LED controller with constant voltage (CV), intended for dimming and control of single-color, Tunable White, RGB and RGBW LED strips. It supports six operating modes, including DALI Device Type 6 (DT6) and Device Type 8 (DT8), thanks to which it offers flexible control options for intensity, color temperature and lighting colors.

The controller works with with an input voltage of 12–48 V DC and has four PWM output channels with a common positive pole. The maximum output current is 5 A per channel at 12–36 V DC a 2.5 A per channel at 48 V DC. The total maximum output power reaches 480 W when powered by 24 V or 48 V DC. The device requires an external constant voltage power supply.

Six operating modes allows you to adapt the controller to a specific type of LED lighting:

• DT6 – dimming of single-color LED lighting.

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

• DT8 RGBWAF – RGBW lighting control.

• DT8 XY – color control using XY color coordinates.

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

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

Depending on the selected operating mode, the controller uses one or two DALI addresses. The mode and addresses can be set directly using buttons and an integrated digital display. The device also supports control via an external button Push DIM, which enables switching on, off, dimming and, in the respective modes, also setting the color or color temperature without the need for a DALI control unit.

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