Electric voltage supply

摘要

A closed-loop control circuit includes an actuating element having a current path and a respective actuating signal input, and a closed-loop controller to interact with actuating signal input. The current path of actuating element is enabled by closed-loop controller when the output current drawn at output connections (3a,3b) is present in predetermined value assigned to respective actuating element. The current path is disabled when the output current drawn at output connections does not lie in predetermined value.
