ことを特徴とする減電圧アラーム。A DC power supply, a load connected to the power supply, a load control switch, first and second voltage determination circuits, and oscillation in response to voltage determination levels of the first and second voltage determination circuits. It consists of an oscillation circuit, a buzzer, and a load drive circuit that responds to the voltage judgment level of the first voltage judgment circuit. When the switch is turned on, the first voltage judgment circuit judges the voltage level of the power supply, and the power supply When the voltage drops below a certain level, it issues an alarm and stops driving the load.
Further, when the switch is not turned on, the voltage level of the power supply is determined by a second voltage determination circuit, and an alarm is generated when the power supply voltage falls below a certain level.
