Gas Discharge Tube Arresters (GDT) are designed to protect electrical systems from overvoltage of various origins, such as lightning, switching and transportation. The VIS400 GDT is one of the most advanced gas discharge tube arresters available on the market and features advanced temperature-dependent breakdown voltage, ultra-low leakage current on and off voltage, and high noise immunity.

The VIS400 is a three-port GDT that includes two voltage ports and a grounding port. When a GDT is in the static state, the current flowing through the ports is zero and the voltage over it remains the same regardless of the load. However, when the voltage on the circuit increases over a certain voltage, called the breakdown voltage, an avalanche breakdown is triggered and the GDT starts conducting current.

This avalanche breakdown is a spontaneous flow of carriers created by impact ionization. The breakdown voltage of GDTs is temperature-dependent and generally increases at lower temperatures. By using active temperature compensation, VIS400 GDTs can maintain a constant breakdown voltage over a wide temperature range. This temperature-dependent breakdown voltage combined with ultra-low leakage current-on and -off voltage makes VIS400 GDTs truly unique.

In order to further reduce the chances of excessive charge entering the system, the VIS400 GDT is equipped with Visicap, an ultra-fast bypass technology that can effectively reduce the amplitude of transient voltages on the system, while maintaining the highest level of noise immunity. As a result, the VIS400 GDT offers enhanced protection for sensitive electronic devices.

The VIS400 GDTs are available in various varieties and sizes depending on the application. They can be used in a wide range of applications such as power supplies, medical equipment, surveillance systems, and industrial control systems. These GDTs are also widely used in aerospace industries, as they provide the highest protection against lightning, while maintaining a high level of noise immunity and reliability.

In addition to its advanced technology and features, the VIS400 GDT is also very easy to install and use. It requires no external control device and its design is compact, making it a perfect choice for various applications. Furthermore, its open enclosure provides excellent heat dissipation, making it a reliable and long-lasting solution.

In conclusion, the VIS400 GDT is a versatile device designed to protect various electrical systems from various voltage sources. Its advanced features such as temperature-dependent breakdown voltage, Visicap technology, and ultra-low leakage current-on and -off voltage make it capable of providing the highest level of protection to sensitive electronic devices. Its compact design and easy installation make it highly suitable for various applications.
