7. Current gear setting
The typical current data sets are for reference when selecting LED fixture models. More current levels can be set by NFC using a mobile APP adjustable in 1mA steps.
8. ON/OFF & Description of Dimming Operation
DALI dimming mode: Connect the power supply to the DALI system, and it can be dimmed by the DALI host. The dimming range is 2-100%.
9. The matters needing Attention
1) The LED driver must be connected to the load before turning on the input power, otherwise the LED driver may be damaged.
2) After the LED drive input is powered off, there will be a residual voltage at the output, which can be maintained for about 3 minutes.
3) Before setting the parameters by NFC, please make sure the driver is powered off.
