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.
