DIMMING OPERATION ELG-75 ◎ 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.
