A GDT or Gas Discharge Tube Arresters (GDT) is an important design element used to protect devices and circuits from damaging lightning strikes or high-voltage disruptions. The CG90LS is a special type of GDT that is specifically designed to protect switched-mode power supplies (SMPS) and remote access networks from lightning or power fluctuations.

Application Field of CG90LS

TV Antenna surge protector, TV antenna booster, indutrial control hardware, security systems, and wireless networks are common applications for CG90LS GDT arresters. This GDT arrester can also be used to protect radio broadcasting transmitters, tower antennas, wireless communication systems, radio Frequency ID (RFID) devices, point-to-point microwave systems, and solar arrays. Due to its high current rating, low voltage drop, and ultra-compact size, the CG90LS arrester is a highly-reliable and cost-effective solution for protecting sensitive electronic and power components.

Working Principle of CG90LS

The CG90LS arrester operates by using a combination of gas tubes and semiconductor technology. The GDT gas tubes provide both spark gap protection and current limiting, and the diode clamps prevent over-voltage spikes from occurring. When a surge or high-voltage event occurs, the CG90LS activates its protective circuit, which first triggers the spark gap of the GDT. The spark gap shunts the incoming surge to the ground, preventing it from reaching the protected circuitry. At the same time, the diode clamps kick in to ensure that the peak voltage remains below the GDT\'s threshold. The combination of GDT and diode clamps also works to reduce the number of high voltage transients getting through, providing an excellent level of surge protection.

Additionally, the CG90LS arrester is designed to dissipate the transient energy during high voltage events and lightning strikes. This reduces the energy coupling between the power distribution system and the protected electrical equipment, ensuring that the risk of damage to sensitive components is minimized. This feature makes the CG90LS an ideal solution for protecting equipment from high-energy transients in harsh industrial environments.

Conclusion

The CG90LS arrester is a special type of Gas Discharge Tube (GDT) Arresters that is designed to protect switched-mode power supplies and other remote access networks from lightning or high-voltage disruptions. This arrester uses a combination of gas tubes and semiconductor technology to provide both spark gap protection and voltage clamping in order to protect sensitive equipment from high-energy transients and lightning strikes. Its high current rating, low voltage drop, and ultra-compact size make it a reliable and cost-effective solution for industrial, commercial, and residential applications.
