Gas Discharge Tube Arresters (GDT)

Gas Discharge Tubes (GDT) are an essential part of many modern electrical circuits. They are used to protect expensive and sensitive electronic components from transient electric surges. GDTs are typically found in power supplies, industrial control systems, electrical installations or medical device systems, and are a must-have component in many high-end applications. GDTs can be found in almost any application where power surges can occur: from the home or office to industrial plants and other data centers.

2046-23-ALF Application Field and Working Principle

The 2046-23-ALF, manufactured by Fujitsu, is a GDT designed for use in applications that require a wide range of protection from transient surges. It features an arc-gap-type construction with a robust stainless steel housing for superior surge protection. It has an integrated voltage level rating of 20kV, and a discharge capacity of 3kA per pole. The 2046-23-ALF is also equipped with slew limitation, which helps prevent sudden surges from causing damage to the system.

The working principle behind GDTs is based on the principle of capacitive discharge. A small electric field is created between the two electrodes in the GDT, called the anode and cathode. When a voltage pulse is applied, electrons are drawn from the anode to the cathode, creating an electric arc. The arc is capable of dissipating the energy of the surge, thus protecting the system from potential damage.

The 2046-23-ALF has a unique design that allows for an adjustable arc voltage level. This can be adjusted from 5 to 10kV, allowing for a better fit with the application’s specific needs. The adjustable voltage threshold also contributes to higher surge protection levels, ensuring a reliable standard of protection.

The 2046-23-ALF is also equipped with advanced surge suppression technology. It features a capacitance control element, which allows for a maximum capacitance and maximum arc gap. This helps to ensure that only innocuous energy is released during surge events, and that no destructive energy is released, thus providing reliable surge protection.

Overall, the 2046-23-ALF GDT is an ideal choice for applications where reliable surge protection is required. With its adjustable voltage level and advanced surge suppression technology, it offers superior protection from transient electric surges. It is designed to provide users with the highest possible level of protection from power surges, while still offering a long-term, cost-effective solution.
