RS485 signal protector, network signal surge protector, control signal arrester, two in one.

Product description

The control signal network lightning protection duo protector uses a multilevel protection circuit. During the latest high speed surge protection, we use the latest high speed surge protection, the reaction speed is fast, the output residual pressure is low, the transmission performance is superior. The product selects the metal shell, the sealing property is good, it has the dustproof and corrosion protection functions, the interface uses the 3pin line terminal and adopts the series mode. It can restrain high voltage surge on line and protect rear end equipment from overvoltage damage. It is suitable for railway communication system, mobile base station, differential station, network transmission equipment such as hard disk recorder, video surveillance equipment, optical terminal and so on, and the data transmission of computer communication system, supervisory control and control system, entrance guard system, automatic control system, security system and so on.

Product specification

Working principle of product

The lightning arrester can effectively protect the power equipment. Once the abnormal voltage appears, the lightning arrester will play a protective role. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power 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.

4. low insertion loss (less than 0.5dB).

5. The transmission rate is high and the frequency range is large.

Use of attention

1. lightning arresters 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. lightning arrester can be easily 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.

4. lightning arrester grounding with the shortest possible line connection. 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.
