第１項記載の停電検知装置。[Claims for Utility Model Registration] (1) A device for detecting disconnection or voltage drop in the AC power supply or DC power supply using an output obtained by replacing the AC power supply or DC power supply with an AC power supply, including a means for rectifying the AC power supply; , means for comparing the rectified pulsating output with a reference voltage, and a triggerable monostable multivibrator that is triggered by the compared output, and the setting time of this monostable multivibrator is set to the period of the rectified pulsating output. A power outage detection device characterized in that the output of the monostable multivibrator is set longer and outputs the output of the monostable multivibrator as a power outage detection signal. (2) The power failure detection device according to claim 1, characterized in that either or both of the reference voltage and the time of the monostable multivibrator are made variable.
