LED Current Selection
Use DIP switches to select output current. Ensure the driver is powered off before setting. Power on again for the setting to take effect.
Note: Setting current while powered on may damage the light fixture.
Example: For LED 3V/pcs, a 9-42V output voltage range can power 3-14 LEDs in series. The maximum number of LEDs in series depends on the actual LED voltage.
| DIP Switch | Output Current | Output Voltage | Output Power |
|---|---|---|---|
| 1 | 100mA | 9-42V | 0.9-4.2W |
| 2 | 150mA | 9-42V | 1.35-6.3W |
| 3 | 200mA | 9-42V | 1.8-8.4W |
| 4 | 250mA | 9-40V | 2.25-10.5W |
| 5 | 300mA | 9-34V | 2.7-12W |
| 6 | 350mA | 9-30V | 3.15-11.9W |

Wiring Diagram
DALI Connection Mode
Input: Connect Live (L) and Neutral (N) wires.
DALI Signal: Connect DA and DA terminals for DALI communication.
Output: Connect LED-W (LED Negative), LED-C (LED Common), and LED+ (LED Positive).
Wire diameter for input/DALI: 0.75-1.5 mm² (22-16 AWG), strip length: 4.5mm-5mm.

- Pry up the protective housing in the side plate position with a tool.
- Pry up the side edge of the tension plate with a tool to remove it.
- Use a screwdriver to connect electrical wires as per the wiring diagram.
