Operating instructions

Dali DT8 is a dimmable LED driver with a built-in DALI-2/Push interface. It offers precise control over Tunable White LED lighting fixtures, allowing for smooth dimming down to 0.1%. With 2 channels of constant current output (350mA to 700mA), selectable via DIP switch, it provides flexibility for various lighting applications. The Hybrid (PWM+PFM) dimming ensures deep dimming without compromising light quality. Compatible with universal DALI masters that support DT8 commands, it integrates seamlessly into existing systems.

While connected with a AC PUSH, the digital display will show “PD” which means Push Dimmer Mode,
operations under Push Dimmer Mode are as follows:
1.1. Click the button to switch ON/OFF
1.2. Press and hold down the button to increase or decrease light intensity to desired level and release it, then
repeat the operation to adjust light intensity to opposite direction. The dimming range is from 0.1% to 100%.
1.3. Memory function after power off or power failure enables the device to memorize the status before power off
while power on again.
