DIMMING OPERATION
※ 2 in 1 dimming function
◎ Applying additive 0 ~ 10VDC
◎ Applying additive 10V PWM signal (frequency range 300~3000Hz):

Dimming input: Additive voltage
Duty cycle of additive 10V PWM signal dimming input
※ Dimming principle for PWM style output
‧Dimming is achieved by varying the duty cycle of the output current.
Duty cycle of output current (%)Duty cycle of output current (%)
Note : 1. Min. duty cycle of output current is about 8% and the output current is not defined when 0%< Iout<8%.
2. The duty cycle of output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.
