Dimming input: Additive resistance

Duty cycle of output current (%)

Note : 1. Min. duty cycle of output current is about 0.15%, and the dimming input is about 6KΩ 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 6KΩ or less than 0.6VDC,

or 10V PWM signal with duty cycle less than 6%.

‧Apply DALI signal between DA+ and DA-.

‧DALI protocol comprises 16 groups and 64 addresses.

‧First step is fixed at 0.2% of output
