DIMMING OPERATION
※ 2 in 1 dimming function
Output constant current level can be adjusted by applying one of the two methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal.
Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.
◎ Applying additive 0 ~ 10VDC
◎ Applying additive 10V PWM signal (frequency range 300Hz ~ 3KHz):
Note : 1. Min. dimming level is about 8% and the output current is not defined when 0%< out<8%.I
2. The output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.

※ DALI Interface (primary side; for DA-Type)
Apply DALI signal between DA+ and DA-.
DALI protocol comprises 16 groups and 64 addresses.
First step is fixed at 8% of output.
