Abstract:
1. Control device for an electro-actuator comprising a first and a second input terminal which are connected, in use, to an electrical energy source; a first and a second output terminal which are connected, in use, to the electro-actuator; and selectively controlled switch means which is activated in order to connect the first and second output terminals to the first and second input terminals in predetermined operative conditions; controlled switch means comprising first controlled switch means which are connected between the first input terminal and the first output terminal and second controlled switch means which are connected between the second input terminal and the second output terminal; the control device comprises: first detector means which are connected to the ends of the first controlled switch means and provide a first signal (V first threshold comparator means which are configured to compare a value correlated to the current flowing in the first controlled switch means with a first threshold value (V wherein the maximum current flowing in the first controlled switching means under normal operating conditions is a function of the current I
