Claims

[Claims for Utility Model Registration] In a device that generates a set voltage or current from an amplifier circuit and connects a load between output terminals P1 and P2, a device that is connected in series to the load and that generates a set voltage or current according to the current flowing through the load. a shunt resistor that generates a voltage; first and second switch means RL1 and RL2 that are respectively inserted into a circuit connected to the two output terminals P1 and P2 and turn this circuit on and off; and a shunt resistor that generates a voltage in the shaft resistor. a rectifier circuit that performs full-wave rectification of the voltage to which the voltage is applied; a smoothing circuit that smoothes the output of the rectifier circuit; a comparator that compares the output of the smoothing circuit with a set voltage; and when the comparator becomes active, the first switch and means 7 for driving off the means and the second switch means.
