After many years manufacturing, sales and engineering of security products, andaccording to the newest IEC criterion, we have developed surge protector suitable for coaxial video, UTP control signal and low-voltage power supply used in security engineering. These protectors overcome the shortcomings of old surge protectors, have the characteristic of big circulation, high continuous withstand voltage, low residual voltage, small attenuation, long life etc. It's realized the most reliable and safe protect mode.
