Abstract
PURPOSE: To increase the repetitive performance of the delay time, by enabling the use of low breakdown voltage components, through constituting the delay circuit of AC relay with the full wave rectifying circuit, series circuit of a resistor and two diodes, and unidirectional triterminal switching element.
CONSTITUTION: When the power supply is applied, the capacitor 34 is charged with the relay 35, full wave rectifying circuits 36 to 39, capacitor 41, diode 42 and resistor 33. After a given time is elapsed, the charging voltage reaches the switching voltage of SBS 32, turning on SCR 32. Thus, the relay 35 is operated with the current of AC half wave. At this time, although the capacitor 41 is charged, when the AC waveform closes to the zero cross, the capacitor 41 is discharged. SCR 41 continues turning on and the operation of the relay 35 is maintained. When the AC waveform closes to the peak, the capacitor 41 is again charged up. AC current is flowed to the relay 36 and the full wave rectifying current is flowed to SCR 31, and the relay keeps the operation. At this time, the residual charge of the capacitor 34 is discharged through SCR and the delay time is repeated, improving the performance
