  • Patent number: 7283338
    Abstract: A power supply device for low-voltage electronic residual current circuit breakers includes an electronic rectifier stage suitable to receive in input a mains voltage and to generate a first unipolar voltage whose value depends on the value of the mains voltage, and an electronic adjustment stage, suitable to receive in input the first unipolar voltage and a current and to generate in output a second unipolar voltage of adjustable value. The electronic adjustment stage performs an active adjustment of the current input to the electronic adjustment stage so as to keep the second unipolar voltage at a predefined constant value.
