検出回路。 An AC/DC converter that converts alternating current into stable direct current, a load to which DC power from the AC/DC converter is applied, a timing circuit that adjusts the application time of DC power to the load, and a signal from the timing circuit. In a circuit equipped with a first switch provided between an AC/DC converter and a load that are opened/closed by the If a voltage is detected by the detection circuit while the timing circuit is outputting a signal to stop applying DC power to the load, or the timing circuit will stop applying DC power to the load. A determination circuit that outputs a signal to the second switch to stop applying the AC power to the AC/DC converter circuit if the detection circuit does not detect voltage while outputting the signal. Anomaly detection circuit.
