て、リレーの制御を行っている。The AC power supply voltage is rectified by the rectifier circuit 14, smoothed by the capacitor 10, and made into a constant voltage by the constant voltage power supply circuit 16. A constant voltage is generated across the constant voltage diode, and a potential (the first voltage) is supplied to the control circuit 6. Figure 2C). The output of the control circuit 6 is reduced in pressure by a resistor 7 and becomes an input signal to a transistor 9. This signal controls the transistor to conduct electricity, and controls the relay by making the relay coil 9 conductive or non-conductive. .

F, the potential across the capacitor 10 is the second
As shown in Figure a, at time T1, the voltage charged in the capacitor 10 begins to discharge and decreases. According to this discharge, the control circuit input voltage also decreases as shown in FIG. Even if the voltage is restored, the input voltage has already dropped to the level at which the control circuit 6 can operate once, so it is easy to reset and malfunction. However, as in the present invention, if the values of the resistors 7 and 8 are set close to the base-eminter voltage of the transistor 9 at which the transistor 9 shuts off, the power supply voltage begins to drop, and the control circuit 6 When the input voltage starts to rise, the transistor 9 shuts off (Fig. 2b) and shuts off before the input voltage of the control circuit reaches v2, and the current 13 flowing through the relay coil 11 is cut off. (time T2). Flow to relay coil 11.

る。In addition, as shown in FIG. 3, a constant voltage diode 17 is connected between the resistor 7 and the control circuit 6.
The voltage remaining after subtracting the voltage generated by the voltage regulator diode from the output voltage of the control circuit is divided by resistor 7 and resistor 8 to control the transistor, but if a momentary power outage occurs, the control circuit output voltage will change. With a slight decrease, the constant voltage diode turns OFF, and the transistor responds well and quickly.
Since it is turned off by pressing f, stable operation is performed.
