Cut Off High And Low Voltage Protection Circuit Diagram. If any device needs 12v to work properly then this can be damaged by increasing the voltage. The ac mains high and low voltage cut off circuit explained in this article is very easy to build and yet very reliable and accurate.
Lm358 pinout details the circuit design. Here is a simple and inexpensive circuit using opamp lm358 to disconnect the equipment during high and low voltage. This circuit automatically cuts the current supply to any appliance from the input circuit.
Lm358 pinout details the circuit design.
This circuit is a very useful auto cut circuit to the protection of any electrical or electronics appliance from high voltage. This circuit automatically cuts the current supply to any appliance from the input circuit. Voltage fluctuations and power cuts adversely affect various electrical appliances such as tv music system refrigerator etc. As shown in the circuit diagram a couple of transistor stages are integrated together along with an output relay which is able to perform the function of super safe voltage guard equipment.
