In the field of information system and communication, the signal surge protector adopts the concept of multi-level protection. The front stage adopts a device with a large flow rate for primary protection to reduce the residual voltage and put the large discharge into the ground.

A coordinator is used for decoupling in the middle. In order to meet the special requirements of the front and secondary protection devices; the secondary uses spd fast response devices for fine protection, reducing the line to the level that the equipment can bear, and quickly limiting the surge voltage without affecting the quality of the protected signal transmission , to achieve a safe level of protection, and ultimately ensure the safety of equipment and personnel.

The data signal surge protector is designed according to the IEC surge protector standard, and is suitable for the signal protection of bus type, analog quantity and switch quantity of various data information systems. Avoid damage to the control system due to the operation overvoltage generated by the electrical control switch during the conversion process and the strong transient magnetic field (induced overvoltage) formed when lightning strikes near buildings or equipment facilities.

Product features: 1. Small insertion loss, low voltage protection level; 2. Fast response time, nanosecond action time; 3. High transmission rate; 4. Large flow capacity for multi-level protection; 5. Standard 35mm rail installation ; 6. Suitable for 2-wire, 3-wire, 4-wire signal line protection
