Abstract
Abstract A cabinet for distribution of electric power controlled by a programmable controller comprising a housing for holding frames, said housing having entering therein a multibus which combines the lines carrying addresses and commands sent by the controller and the power supply lines, said housing having leaving therefrom a plurality of distribution lines; said frames functioning to hold modular power elements in side-by-side arrangement, said frames being each provided with a multibus branch connected to the housing multibus input and fitted at the location of each module with a terminal for each command line and two address terminals, said address terminals having a voltage applied to them when the location is selected by the means of selection present in said multibus branch of the frame; supply buses connectable to the housing power input and being provided with plug-holes for connection of the modular elements; said modular elements being connectable to the multibus and buses of a frame at any location of said frame and having memories which store the commands from the controller upon authorization to read given by the address selection of the frame, said modular elements distributing the currents for execution of the controller's commands.
