SH250

A Gas Discharge Tube (GDT) arrestor is an electrical device that is used to prevent circuit damage from lightning strike and other high-voltage events. The SH250 series of GDT arrestors use a cylindrical gas-filled tube to act as a spark gap for the protection of sensitive electronic circuitry. The SH250 technologies offer both high performance and low cost, making them a great choice for a wide variety of applications.

Working Principle of SH250 GDT Arrestor

The working principle of the SH250 GDT arrestor is based on the use of a gas-filled spark gap to conduct current in order to reduce a voltage spike to a safe level. When an external voltage spike is applied on the GDT, the gas in the tube ionizes and fills with electrons and ions. This causes the voltage across the spark gap to be reduced, as the electrons and ions collide with each other and with the walls of the tube, creating a conducting current path across the gap.

When the voltage spike drops below a certain level, the gas again returns to its non-conducting state, and the voltage across the gap increases again. This process of conducting and re-conduction repeats itself every time the external voltage is applied, allowing the GDT to limit the voltage spike to a safe level. The SH250 GDT arrestors also feature built-in surge protection to further protect sensitive electronics.

SH250 Application fields

The SH250 series GDT arrestors can be used for a wide range of applications such as communication networks, consumer appliances, medical equipment, computers, and more. The devices can also be used in industrial, automotive, and military applications. These GDTs offer a high performance-cost ratio, enabling designers to cost-effectively protect their products against voltage spikes.

The SH250 series GDTs are also available in a range of sizes and gas formula combinations, allowing designers to select the optimal GDT for their project. The devices are designed for easy setup and use, allowing for easy installation and maintenance.

Conclusion

The SH250 series of gas discharge tube arrestors are an economical and effective solution for protecting circuits from high voltage spikes and lightning strikes. The devices are easy to install and use, and are available in a range of sizes and gas formulas to suit various applications. With its low cost and high performance, the SH250 GDTs are a great choice for a wide range of applications.
