Claims (1)
を平滑する平滑コンデンサからなる電源回路にお
いて、上記整流回路と平滑コンデンサとの間に発
光ダイオードを直接接続し、その発光出力の有無
によつて導通制御される受光素子を備え、停電検
出することを特徴とする停電検出回路。 In a power supply circuit consisting of a rectifier circuit that rectifies AC input and a smoothing capacitor that smoothes the output voltage, a light emitting diode is directly connected between the rectifier circuit and the smoothing capacitor, and conduction is controlled depending on the presence or absence of the light output. What is claimed is: 1. A power outage detection circuit comprising a light-receiving element that detects a power outage.
