The KNX-DIM21 is a universal two-channel dimming actuator (up to 300 W per channel).
It supports light sources supplied directly from the 230V AC mains or through a transformer, automatically detects loads as low as 2W, determines their type (resistive, inductive or capacitive), and selects the appropriate control characteristic.
It provides smooth light control and can turn the light on/off, dim it down/up, set the power by using a predefined scene or another function via the KNX bus. It also detects damage to the light source and sends notification about these events. The front panel allows direct control of each channel and visualisation of its status.
