Indoor lightning arrester ac SPD 40KA power surge protection device

Surge arrester suppress surge Will not be destroyed by low voltage lightning

product description

Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It is an electronic device for providing safety protection for various electronic equipment, instruments and communication lines. When the peak current or voltage is suddenly produced in the electrical circuit or communication line because of the external interference, the surge protector can guide the shunt in very short time, thus avoiding the damage of the surge to other equipment in the circuit.

Working principle of product

When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.

Use of attention

1. lightning protector's input port (IN) is connected to the signal channel, and the output terminal (OUT) is connected with the input end of the protected device, so it cannot be connected to the reverse side.

2. the standard RJ45 interface can be conveniently connected to the front end of the protected device, and the grounding path should be as short as possible, and the length should not exceed 1.5 meters.

3. lightning protector is between the protected device and the signal channel.
