Brief introduction
The signal surge control protector is designed according to the standard of IEC and GB surge protector. It is suitable for communication lines, telemetry signals, remote control signals and other signal devices, so that it is free from induced overvoltage, operation voltage and electrostatic discharge. The form of interface is decided by standard screws, and it can protect 1-2 lines. This product adopts modular 35mm guide rail installation design, which is very convenient for installation and maintenance.
Product features
1. using ultra low capacitance design, the signal transmission characteristic is good.
2. the off state leakage current is extremely low, which does not affect the normal operation of the
device.
3. energy saving, environmental protection, easy installation, suitable for all kinds of standard interface types.
Use of attention
1. before the protector is connected to the system, check the grounding resistance of the grounding grid first, which should meet the requirements of the specification.
2. connect protector to the front end of the protected device, and it must be connected reliably.
3. screwdriver loosens the screw on the terminal of the surge protector. First, the system signal line is connected to the input end of the surge protector, the output end is received from the protected equipment end, not the reverse, and the connection part of the connection terminal is reliable.

Working principle of product
The control signal surge protector is connected to the front end of the protected equipment. When the transmission line is impacted by the inductive thunder and other transient overvoltage, the impact current is discharged to the earth through the protection branch of the surge protector, and the output voltage is placed in the allowable voltage range of the equipment, thus ensuring the safety of the operating equipment.
