◎ Applying additive 0 ~ 10VDC
◎ Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
◎ Applying additive resistance:
Note : 1. Min. dimming level is about 6% and the output current is not defined when 0%< out<6%.I
2. The output current could drop down to 0% when dimming input is about 0k or 0Vdc, or 10V PWM signal with 0% duty cycle.Ω

※ 3 in 1 dimming function (for B/AB-Type)
Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance.
Direct connecting to LEDs is suggested. It is not suitable with additional drivers. to be used
