DIMMING OPERATION
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 to be used with additional drivers.
Dimming source current from power supply: 100 A (typ.) μ
LDC-80 series
◎ Applying additive 0 ~ 10VDC
◎ Applying additive 10V PWM signal (frequency range 100Hz ~ 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.
3. To ensure the dimming performance at low dimming level,output current must be over 80mA.
