Quick Guide

The Sunricher 12W DALI DT8 LED Driver is a constant current power supply designed for Tunable White LED lighting. It features a 2-channel output with a selectable current range from 100mA to 700mA via DIP switches. The device supports DALI-2 and Push dimming interfaces and is compatible with universal DALI masters that support DT8 commands.

Safety and Warnings

Do not install the device while power is applied.
Do not expose the device to moisture.
Ensure the installation complies with local electrical codes.
This is a Class II power supply with a fully isolated plastic case.

Installation and Wiring

The driver requires connection to an AC power source (200-240V), a DALI bus, and the LED output channels.

Wiring diagram for DALI bus and LED connection

AC Input: Connect to the L and N terminals.
DALI Bus: Connect to the DA and DA terminals.
LED Output: Connect the LED fixture to the WW (Warm White) and CW (Cool White) terminals.

Refer to the wiring diagram for the correct terminal layout. Ensure all connections are secure before applying power.

Operation and Settings

The output current is configured using the DIP switches located on the device. Match the switch positions (1, 2, 3, 4) to the desired current output as specified in the product data table (e.g., 100mA to 700mA). The DALI address is assigned automatically by the DALI Master controller.
