DC-DC Step-Up Constant Current LED driver
Application Notes:
1.The positive and negative input terminals must be connected correctly and negative voltage can not be input
to avoid damage to the power supply.
2.Due to the large input current, please pay attention to the voltage drop of the wiring, to ensure the power
supply to work properly.
3.When using the LEDS of different forward voltage, please pay attention to the min Load of DA-type to ensure that
LED lights went out after DALI dimming off.
