Dimming input: Additive voltage
Duty cycle of additive 10V PWM signal dimming input
(N=driver quantity for synchronized )dimming operation
Dimming input: Additive resistance
※ 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-:
1 ~ 10VDC, or 10V PWM signal or resistance.
Direct connecting to LEDs is suggested. It is not suitable with additional drivers. to be used
Dimming source current from power supply: 1 0 A (typ.) 0 μ
