Audio data line lightning arrester HD-XC-AU

Audio data line lightning arrester The product is suitable for the protection of a monitor head, a decode circuit, an entrance guard data line, background music, a visual-speaking system, an intelligent water meter, an intelligent gas meter, an intelligent electric meter, a wide-used ID system and a fireproof alarm line, and prevents the damage of line induction overvoltage equipment due to earth potential increase, has low output residual voltage, little insertion loss and double over-current protection, and is suitable for the protection of the ports such as the RJ11, connection terminals, RS232 and so on. And the protective lines can be divided into the single circuit type, double circuit type or multiple-circuit type.
