SEE DIY compressor time delay circuit. Protect your compressor when power outage and Electrical fluctuations. Using normal parts and cheap.
For learn about MOSFET. I recommend Time Delay circuit easy to make and long time and a few parts than normal transistor
The surge protection circuit important! Sometimes, our electrical appliances may damage easily by little high voltage surges. We can protect this problem.
This is the simple time delay circuits using JFET. Which it will alarm with a buzzer sound. In circuits have a few parts. And an important component is 2N3819-FET---Small Signal…
