The 1-channel LED dimmer with 4-in-1 input from Proled is digitally controllable and addressable via a DALI interface. Control can also be achieved through a 10k Ohm potentiometer, a 1-10 V control voltage source, a button with PUSH-DIM function, or phase-cut and phase-on dimmers (Triac). The output voltage corresponds to the respective supply voltage of 12-24 V.
