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 B-type model 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.
Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
2.The LED lighting fixture can be turned ON/OFF by the switch.

There are two major kinds of LED drive method "direct drive" and "with LED driver".
Typical LED power supply I-V curve
A typical LED power supply may either work in "constant voltage mode (CV) or constant current mode (CC)" to drive the LEDs.
Mean Well's LED power supply with CV+ CC characteristic can be operated at both CV mode (with LED driver, at area (A) and CC mode (direct drive, at area (B).
