Control module for static voltage stabilizers in lighting networks, which consists of a supply transformer; rectifiers/regulators capable of stabilizing and generating the power supplies for analog and digital circuits; comparators between the output voltage and the reference voltages; analysers for raising/lowering the voltage that arrives at a selector module; switches for selecting the appropriate voltage tap of a transformer, for keeping it stabilized within the pre-set limits; and means of protection against any surge current and/or earth leakage which, in an emergency, block the operation of the module and generate an order to change to a by- pass circuit. Can be used in static voltage stabilizers for electricity supply lines. <IMAGE>
