DALI-2 Dimming Operation

The MEAN WELL XLG-320-DA2 Series includes DALI-2 dimming control for LED lighting systems that require digital dimming, addressable control, and flexible lighting management.

According to the datasheet, the DA2 type supports DALI-2 control technology with output current adjustable via the built-in potentiometer. The DALI interface uses DA+ and DA- control wires, and the DALI protocol supports 16 groups and 64 addresses.

With DALI-2 dimming, the XLG-320-DA2 Series is suitable for street lighting, floodlight lighting, bay lighting, stage lighting, fishing lighting, horticulture lighting, and other projects where controlled dimming and outdoor LED driver reliability are required.

DALI-2 Control Interface

The DALI signal is applied between DA+ and DA-. The driver uses a purple wire for DA+ and a pink wire for DA-, while the LED output uses red for V+ and black for V-.

This makes the XLG-320-DA2 Series suitable for lighting systems that require a DALI-2 LED driver with separated power output and digital dimming control wiring.

Minimum Dimming Level

The XLG-320-DA2 Series supports DALI-2 dimming with a minimum level of 8%. This is useful for applications where the lighting system needs controlled low-level output instead of simple ON/OFF operation.

For projects with strict dimming performance requirements, users should confirm the controller compatibility, dimming range, LED module load, and final system behavior before mass installation.

Output Current Adjustment

The DA2 version supports output current adjustment via the built-in potentiometer. This allows the output current range to be matched with the LED module requirements during system design or installation.

XLG-320-L-DA2 supports a 500–1400mA adjustment range, XLG-320-M-DA2 supports a 1050–2800mA adjustment range, and XLG-320-H-DA2 supports a 2800–7420mA adjustment range. These options help users select the correct output range for different LED module voltage and current requirements.
