Abstract

PURPOSE: To enable costs to be reduced by standardization of an overcurrent detector and the like by providing a current transformer and decision processing circuit mechanically separated therefrom.
CONSTITUTION: A full-wave rectifying diode bridge 2 is connected to the secondary coil of a current transformer 1, and further, a regulating resistor 3 is provided as its load. The voltage output thereof serves as the output of a diode 4 for the purpose of preventing the entry of current from the outside. It is possible to change the value of the secondary output voltage by changing the value of the regulating resistor 3. The current transformer 1 is connected to a mechanically separated decision processing circuit.
