◎ Applying additive resistance: Note : 1. Min. duty cycle of output current is about 0.15%, and the dimming input is about 6K Ω or 0.6VDC, or 10V PWM signal with 6% duty cycle. 2. The duty cycle of output current could drop down to 0% when dimming input is less than 6K Ω or less than 0.6VDC, or 10V PWM signal with duty cycle less than 6%. +V -V DIM+ DIM- + - “ DO NOT connect "DIM- to -V" Additive Resistance 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Short 10K/N 20K/N 30K/N 40K/N 50K/N 60K/N 70K/N 80K/N 90K/N 100K/N 120W PWM Output LED Driver PWM- 120 se r i es ‧ Apply DALI signal between DA+ and DA-. ‧ DALI protocol comprises 16 groups and 64 addresses. ‧ First step is fixed at 6% of output ※ DALI Interface (primary side; for DA-Type) 0% LED Strips + - 6K/N 10K/N 0.15% 10% (N=driver quantity for synchronized dimming operation ) Dimming input: Additive resistance Duty cycle of output current (%) File Name:PWM-120-SPEC 2019-12-26
