The apparatus controls and manages electrically-driven users, and comprises: an electrical transformer (1), provided with a plurality of outputs (TM, TS) at various voltages, each of which is connected to an input of a power contactor (2), an output of which contactor (2) is connected to supply phases of a user (5). The apparatus further comprises at least one sensor (4) which detects a parameter connected to an operative state of a user and provides an electrical control signal, proportional to a value of the parameter, to a program logic control (6) of known type which in turn sends in output on-off control signals that actuate opening and closure of the contactors (2). |
