V18ZS3 application field and working principle

The V18ZS3 is a voltage protection device typically used to protect electronic equipment from the damaging effects of surge voltages. It has a dual function of limiting and clamping, offering greater protection to sensitive electronic circuits. The working principle and application of V18ZS3 will be discussed below.

The V18ZS3 is a Varistor, which are a class of nonlinear electronic components. It consists of two metal plates, separated by a nonlinear resistor. The resistance between the two plates is designed to decrease as the voltage increases. This allows the varistor to regulate the amount of current flowing through the circuit when exposed to an electrical surge.

As the voltage increases, the resistance between the plates decreases, causing current to be diverted away from the sensitive electronic components. When the voltage drops again, the normal resistance resumes. By using this method, the V18ZS3 is able to provide protection to your electronic components from surges.

The V18ZS3 is designed for use in both AC and DC applications. It can be used as a protective device for AC or DC power supplies or any other electrical circuit where voltage protection is needed.

The V18ZS3 is also designed to be used in high-voltage applications. It has a maximum operating voltage of 1200V, making it suitable for use in industrial and commercial equipment. It can also be used to protect both mains and low-voltage components in electrical circuits.

The V18ZS3 also features a "varistor gap". This allows it to limit the current flowing through the Varistor if it is exposed to a high voltage. This protects the sensitive electronics in the circuit from becoming damaged if a surge occurs.

The V18ZS3 is designed to provide protection from both electrical surges and static electricity. It is not suitable for use in high-temperature applications, however, so be sure to keep it away from sources of heat.

The working principle of the V18ZS3 is relatively simple. When the voltage of the circuit increases, the resistance between the two plates decreases, allowing current to be diverted away from the sensitive electronic components. When the voltage returns to normal, the resistance increases and the current is diverted back to the components.

The V18ZS3 is an ideal choice for protecting various electrical circuits from sudden surges. Its dual function of both clamping and limiting offers greater protection to the sensitive electronics in the circuit, and can be used in both AC and DC applications. It is designed with a "varistor gap" to protect against static electricity, and is suitable for use in industrial and commercial equipment with a maximum operating voltage of 1200V.
