DIMMING OPERATION
ELG-150-C
※
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 to be used with additional drivers.
‧
Dimming source current from power supply: 100 A (typ.)
μ
◎
Applying additive 0 ~ 10VDC
◎
Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
◎
Applying additive resistance:
Note : 1. Min. dimming level is about 8% and the output current is not defined when 0%<
I
out<8%.
2. The output current could drop down to 0% when dimming input is about 0k
Ω
or 0Vdc, or 10V PWM signal with 0% duty cycle.
