Device allowing the selective graduation of a plurality of electric power elements by using only a single line of passive bus for the distribution of the controls and energy. The coupler (M12X) based on a microprocessor, processes the data (analog or digital) and transmits in series the controls in the form of digital packets. The passive bus (CANALIS) is a tetrapolar electric line (two poles for the controls and two other poles for the monophased alternating energy 200 A) comprising junction windows spaced by 30 cm. The dimmer (IGNIS), as many as X, is an intelligent serial receiver based on a microprocessor and connectable to any of the junction windows of the bus: -its physical address is programmable on a selector or on EPROM; -it performs the functions of instantaneous graduation, delayed graduation, change of logic address; -it delivers a graduated power of 1 KVA. The device according to the invention is particularly intended to the control of light projectors of spots in the field of scenic or stage equipments.
