12V24V220V single channel power supply arrester video 485 control signal lightning arrester.
Product description
The control signal lightning arrester (SPD, surge protector) is mainly used in the data control signal of the industrial control system, the communication special line, the telemetry signal and the remote control signal. It is applied in the 1-2 and 2-3 areas of the lightning protection zone.
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. with over current, over voltage and clamping three protection functions.
2. when lightning strikes and invades, no need to stop electrical equipment, and does not affect the operation of normal equipment.
3. The design of the appearance is novel and the volume is small.

Use of attention
1. system signal lightning arrester can be installed in the LPZ0-1 area or directly connected to the front end of the protected equipment (or system), and the closer the better from the protected equipment (or system).
2. the control signal lightning protector can be conveniently fixed on the 35mm electric rail.
3. "IN" connects the lead end, "OUT" connects the protected equipment (or system) end, "1" and "3" as a signal channel, "2" and "4" as a signal channel. When installing, the two ends must be laid separately, and not be tied together to prevent the two induction.
