High voltage Protection circuit This is a High voltage Protection circuit that Protects the circuit from high voltage to any device by the automatic cutoff using the popular ic 741. Note- Connect the load with NC pin of the relay When the input voltage at Non- inverting pin of op-amp 741 is crossed over the …
 Overvoltage autocut circuit diagram This Autocut circuit is very easy, simple and very useful. Only One transistor and some other components are used in this high-voltage protection Auto circuit. The load is connected with the NC (normally connected ) Pin of the relay. This circuit is a very useful auto-cut circuit to protect of any …
