TRSS-485 control signal surge protection device

Model: TRSS-485

Color: white / red

Verification: CE

product description

Control signal lightning protection device is used for transmission protection of sensitive control signals. It is widely used in lightning protection of various control signal lines such as computer communication systems, monitoring and control systems, access control intercom systems, automatic control systems, and data transmission of security systems. Surge protection. Typical for computer RS485, RS422RS232 and other communication serial ports. Protect it from lightning induced voltages, grid voltage fluctuations, electrostatic discharges, and shock surge voltages

Product Features

1. Ultra-low capacitance design, good signal transmission performance

2. Low insertion loss to ensure smooth lines

3. Small VSWR and wide operating frequency range

4. Better shielding performance

Use attention

1. Connect the lightning protection device (SPD) between the line and the device port to be protected. Connect the grounding port on the SPD to the ground net with multiple strands of copper wire, and ensure that the grounding resistance is not more than 4 ohms.

2. When installing, make sure that the '1' screw is installed in place to make the line bond firmly. After installation, use a multimeter to test whether each signal line is turned on. Do not install the SPD with power, otherwise the SPD

3. The lightning protection device does not need long-term maintenance when it is not required to be installed. It only needs routine maintenance of the system; if there is a problem in signal transmission during use, the signal transmission returns to normal after replacing the surge protector. The surge protector is damaged and needs to be repaired or replaced.

Product specifications

Product working principle

TRSS-485 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.
