Teaching how to make a 30 amp city electric protector

If you look around you, you will see many electrical devices such as: TV, tape recorder, computer, refrigerator, cooler, stove, etc., which are more or less exposed to the dangers of city electricity fluctuations; And of course, the use of electrical protection circuit seems necessary for the health of these devices.

Voltage Protection Circuit, which is also known as city power protection module, refrigerator protection board, TV protection board and computer protection device, etc., is an electronic device, which when there are changes such as voltage increase, drop The voltage, extreme fluctuation and the time of disconnection or connection of the city electricity cuts off the electrical devices connected to the city electricity; And after the city's voltage reaches its desired natural value, it supplies electricity to the connected devices.

This work helps to avoid damage to household and industrial electrical equipment to a great extent when there is a problem in the city's electricity.

There are different types of electrical protection circuit and according to the type of consumer, it has different outputs; But since a strong protector can be used for devices with lower power, we will teach you how to make a 30 amp power protection circuit that will meet almost all your needs in the field of protecting electrical and electronic devices.

The best features of the city's electric protection circuit
design in small dimensions; so that it can be embedded in a very small box.
Editability; You can edit the PCB file of this circuit in the Altum Designer software and make changes such as removing or changing the logo, phone, website link and other writings on the board.
Setting the connection delay time from 3 seconds to 5 minutes
The connection delay time is different for different devices. For example, the refrigerator and freezer need to be delayed for about 5 minutes and the computer for about 30 seconds to 1 minute; And you can do this by changing the potentiometer built into the power protection circuit.
Very little construction cost
You can make this circuit with the lowest cost and use it as an air conditioner protector, refrigerator protector, TV protector, computer protector or any electrical and electronic device that needs protection.
