Product specifications

working principle

The control signal surge protector is connected in series with the front end of the protected device. When the transmission line is subjected to induced lightning and other transient overvoltage surges, the inrush current is discharged to the earth through the protection branch of the surge protector, and the output is output. The voltage is clamped to the voltage range allowed by the device, thus ensuring the safety of the operating equipment.

Use attention

1. This product is connected in series.

2. Select the product with the same interface type as the protected device.

3. The IN of the lightning arrester is the input, the OUT is the output, the input terminal is connected to the external line, and the output end is connected to the input end of the protected device.

4. The PE wire of the lightning arrester must be reliably connected to the ground wire of the lightning protection system. The connection wire is required to be short, thick and straight.
