装置。 An output terminal to which a load is connected via a power supply cable, and whether to apply a first voltage to the output terminal or to eliminate application of the first voltage to the output terminal according to an input operation command signal. First thing to do
a power source, a second power source that outputs a second voltage, and whether the second voltage is applied to the output terminal or to a simulated load whose impedance is approximately equal to the load depending on the input operation command signal; a voltage switching circuit that detects a current flowing through a circuit from the second power source to the voltage switching circuit, and outputs a first signal immediately when the current flows, and outputs a second signal after a predetermined period of time has elapsed; a detection circuit; and an alarm circuit that outputs an alarm signal when the first signal and the second signal are input; Load power supply characterized in that the second voltage is applied to the simulated load, and when the first power supply eliminates the application of the first voltage to the output terminal, the second voltage is applied to the output terminal. Device.
