ABSTRACT:
A device for controlling a motor unit which displaces a screening unit which includes a power supply with at least one controlled electronic switch designed to feed a regulated electrical output to the motor unit and a control loop with a circuit which detects the difference between the value of the electrical output produced by the power supply and a reference value, and wherein the reference value is selected for the electrical output as a function of input signals received by the device.
