Power frequency 0-5 minute delay circuit diagram
Source: InternetPublisher:3228 Keywords: Power frequency delay circuit circuit diagram RC Updated: 2020/10/14
The frequency 0~5 minute delay circuit is shown in the figure below. This circuit uses a thyristor trigger circuit composed of a double-gate field effect transistor RC A40841. The value of R determines the duration of the delay control. R is equal to 60MΩ (L RC type CGH type resistor), the maximum delay time available is 5 minutes. The triac can drive a large current resistive load or a reactance current load. In the temperature range of -25~+60℃, the error is within 10%.
