| The CX series control signal surge protector is designed and manufactured based on IEC and GB standards, using PRE-ETS (Surge Energy Intelligent Interception and Absorption System) patented technology for ground free lightning protection. It has a maximum current capacity of 10kA and standard terminal connectors, which can protect two communication lines. It can select the most appropriate limiting voltage for different lines and is suitable for surge protection of camera gimbals, attendance machines, access control, barrier gates, and other RS485 communication line equipment. |
