Functional description DIMMbox
The DIMMbox and the connected LED(s) are powered by the power supply / LED driver at the input if the DIMMbox.
The dimming function is achieved by pulse width modulation control (PWM) at the LED minus output. Switching frequency is around 600Hz.
Product information “DIMMbox”
DIMMBox is a unique dimming solution which provides a single unit, cost effective and highly efficient solution for PWM dimming. With a switching frequency of 600Hz it provides flicker-free and noiseless dimming from a variety of inputs – DALI; 1-10V Analog and Switch Dim/Push Dim.
DIMMBox has been designed to work best with the LT driver families however it can potentially be used to dim in tandem with appropriate LED drivers as well.
