ABSTRACT:
The device is designed to give a signal for the control of the ballast signal of a switched supply by using an index value signal. To benefit from the advantages of a digital control, the control signal is prepared as a function of logic values, pre-programmed in an encoding memory. The value of the index value signal at a given instant defines a starting and an ending of a zone in the encoding memory, and the cyclical reading of this zone through reading means gives the control signal.
