protection, monitoring signal, lightning protector
Product description
The control signal lightning arrester is a lightning protection
measure developed by Zhejiang tohr Electric Co., Ltd., which is
independently developed for signal circuit protection. It is
suitable for signal equipment such as communication line, telemetry
signal and remote control signal to protect it from the damage
caused by induced overvoltage, operating voltage and electrostatic
discharge. It is typically used in communication serial ports such
as computer RS485, RS422RS232 and so on. It is protected from
damage caused by lightning induced voltage, grid voltage
fluctuation, electrostatic discharge and impact voltage.
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.
Product features
1. using ultra low capacitance design, the signal transmission
characteristic is good.
2. energy saving, environmental protection, easy installation,
suitable for all kinds of standard interface types.
3. the coefficient of standing wave is small and the range of
working frequency is wide

Use of attention
1. when installing, make sure that the "one" screw is installed in
place, making the line combination firmly. If the installation is
finished, the multimeter can be used to test whether the signal
lines are connected. Do not install SPD on live line, otherwise it
may damage SPD and equipment to be protected.
2. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
3. lightning arrester should be connected to the shortest possible
line. The protector grounding adopts terminal grounding mode, and
the grounding wire must be connected to the lightning protection
ground wire (or the enclosure of the protected equipment). The
shielding wire of signal can be directly connected to the grounding
terminal.
