◎ Applying additive resistance:
Note : 1. Min. duty cycle of output current is about 0.15%, and the dimming input is about 6K or 0.6VDC, or 10V PWM signal with 6% duty cycle.Ω
2. The duty cycle of output current could drop down to 0% when dimming input is less than 6K or less than 0.6VDC,Ω
or 10V PWM signal with duty cycle less than 6%.
