Gas Discharge Tube Arresters (GDT)

Gas discharge tube arresters (GDT) are invaluable in protecting electronic devices from potential damage due to over-voltage transients. A GDT is a Triggered device, that works on the concept of exceeding a threshold voltage, when a voltage spike reaches a certain point, the GDT is triggered and the current is safely redirected. SL1021B150R GDT is no exception; it operates within the range from 8 V to 15 V DC and is primarily designed for surge protection of telecommunications equipment.

SL1021B150R Application Fields

SL1021B150R GDT are ideal for use in any application where over-voltage transients can cause damage to the installed equipment. Common applications include electrical power distribution and protection, telecommunications, process control, electronic component protection and many other industries where components must be protected from lightning induced voltage transients. This GDT is also certified to the UL1449 fourth edition for applications to telecommunications, process control, and information technology enclosures.

SL1021B150R Working Principle

The SL1021B150R GDT is constructed with a pair of electrodes inside a sealed gas-filled container. When the applied voltage reaches the threshold trigger point, the gas inside the tube becomes ionized, causing a rapid increase in the current flow. This surge of current is redirected by the electrodes, forming a low impedance path to ground. This results in the suppression of over-voltage transients, protecting the connected equipment from damage.

Once the transient has been diverted, the GDT resets itself and is ready for the next voltage surge. This automatic resetting capability makes GDTs ideal for applications where continuous protection is needed, such as telecommunications and industrial processes. With proper installation, the GDT can effectively protect equipment from a wide range of voltage levels.

In conclusion, the SL1021B150R Gas Discharge Tube arrester is an ideal choice for protecting equipment from voltage spikes in many different industries. Its wide range of operation, UL1449 certification, and automatic resetting capability make it an ideal device for a variety of applications.
