VS450SM

Gas Discharge Tube Arresters (GDT)

VS450SM application field and working principle are two important aspects of research concerning Gas Discharge Tube Arresters (GDT). GDT’s are the most widely used devices for surge suppression and lightning protection in electrical power distribution systems. The VS450SM is an epoxy-coated GDT module designed to protect digital and analog power electronic circuits from high voltages and fast transient surges. A typical application of the VS450SM is on the board-level of industrial equipment, such as Uninterruptible Power Supply (UPS).

Application Field of the VS450SM

The VS450SM GDT module is designed to be a reliable surge protection device in a wide variety of industrial applications. It is a component with low resistance and transient voltage protection in 50-450V systems. These applications include:

• Servo motor drives
• Industrial robots
• Control system power supplies
• Telecommunication telecom systems
• SCADA systems
• UPS systems

The VS450SM is an ideal device for applications where there is no room for error. It is highly resistant to false triggering and surge damage in sensitive and critical power systems. As such, it is a valuable asset in protecting digital and analog electronics within these systems.

Working Principle of the VS450SM

The VS450SM GDT module consists of a light-weight, epoxy-coated housing, with a cylindrical anode layer and a perforated cathode layer between two layers of electrode material. The anode layer is made of a thermally-stable polymeric material, which is designed to provide a high degree of protection against electric shock and fast-transien surges. When a surge is detected, the anode layer and cathode layer form a path between the electrodes allowing an excess current to flow. This current then disperses the surge, thus preventing any negative impacts it might have had.

The VS450SM also features a leak rate of less than 5mA, which ensures that no more than a few volts of leakage current passes through the arrester. This is important in protecting sensitive electronics from prolonged exposure to high voltage spikes.

An additional feature of the VS450SM GDT module is its ability to reset itself after a surge. In other words, the current flowing through the device dissipates quickly, allowing the device to reset to its original state. This helps the module to continue to provide protection against subsequent surges, without the need for expensive repairs or replacements.

Conclusion

The VS450SM application field and working principle are essential aspects to consider when choosing a surge protection and lightning protection device for industrial equipment. Its resistance to false triggering and surge damage, and its ability to reset itself make the VS450SM an ideal device for protecting sensitive electronics from high voltage spikes and fast transien surges.
