Claims

[Claims for Utility Model Registration] (1) A power switch connected to a main power supply, and an abnormal voltage detection circuit section inserted between the power switch and a load to compare the main power supply voltage and a reference voltage;
It is equipped with a switching circuit section that switches the output of the abnormal voltage detection circuit section from one terminal to which a load is connected to the other terminal to cut off the main power supply, and an alarm generating section coupled to the other terminal of the switching circuit section. A power supply alarm circuit characterized by: (2) The power supply alarm circuit according to claim 1, wherein the alarm generating section is comprised of a buzzer that generates a sound and a light emitting element that generates light. (3) The power supply alarm circuit according to claim 1, wherein the alarm generating section is comprised of an artificial sound generating section that generates an artificial voice and a light emitting element that generates light.
