※ Dimming principle for PWM style output
Dimming is achieved by varying the duty cycle of the output current.
Duty cycle of output current (%)
Duty cycle of output current (%)
Note : 1. Min. duty cycle of output current is about 8% and the output current is not defined when 0%< out<8%.I
2. The duty cycle of output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.
