Usage Tips:[Built in gas charging surge arrester elements] The design of surge protector focuses on high safety. The device has built-in gas charging surge arrester elements, which can discharge and ground the surge when the surge voltage exceeds the specified level. [Repeatable surge discharge and recovery] The device can repeat surge discharge and recovery operations as required. It does not actually need to be replaced. [Suez arrester elements ] If the arrester elements is , it can be easily replaced with a elements. [ excellent high-frequency characteristics] The coaxial structure of the equipment ensures excellent high-frequency characteristics, broadband, low loss and VSWR. [1/4 wavelength short circuit principle] The surge protector has the 1/4 wavelength short circuit principle, and has good protection effect. The structure is simple, firm and easy to install. [Suez arrester elements ] If the arrester elements is , it can be easily replaced with a elements.
