Dimming connection diagram for turning the lighting fixture ON/OFF :

Using a switch and relay can turn ON/OFF the lighting fixture.

※Using the built-in dimming function on LPF-40D can't turn the lighting fixture totally dark. Please refer to the connection method below to

achieve 0% brightness of the lighting fixture connecting to the LED power supply unit.

1.Output constant current level can be adjusted through output cable by connecting a resistor or 1~10Vdc or 10V PWM signal between DIM+ and DIM-.

2.The LED lighting fixture can be turned ON/OFF by the switch.
