Signal Surge Protector Manufacturer: Functional Characteristics of DC Power Arrester

DC power arresters are generally used for signal overvoltage protection of low-voltage power supply systems to avoid damage to equipment caused by induced overvoltage, operating overvoltage and electrostatic discharge. DC power arresters have multi-level protection, high current capacity, and low limit Voltage, fast response time, etc.

Generally, it is used at minus 40 to 70, the relative humidity is less than 95%, and the atmospheric pressure is between 70 and 10 6千帕.

Signal Surge Protector Manufacturer: Working Principle of Power Arrester

The surge protector is usually connected in series at the front end of the protected equipment. The transmission line is favored by induced lightning or other transient overvoltage shocks. The surge current will be discharged to the ground through the protection branch of the surge protector, and the output voltage will be maintained within the allowable voltage range of the equipment to ensure the safety of the operating equipment. Signal Surge Protector Manufacturer: Power Arrester Installation Instructions

1. Before the DC power arrester is connected to the system, the grounding resistance of the grounding grid should be checked and meet the requirements of relevant national and enterprise specifications.

2. Connect the DC power arrester reliably to the front end of the protected equipment.

3. Connect the grounding wire of the DC power arrester to the protective grounding bus as short as possible.

At present, in the information age, various electronic equipment and communication equipment are becoming more and more complex, and the requirements for the environment are getting lower and lower. However, the phenomenon of lightning in nature is inevitable. Lightning will invade electrical equipment, cause instantaneous overvoltage, damage to electronic equipment or components, and even cause accidents. If the transmitted or stored data is lost, or the local area network is paralyzed, it will cause serious economic losses, therefore, it is very important to choose a DC surge protector suitable for the surge protector.

Signal Surge Protector Manufacturer: How to Select DC Surge Protector for Signal?

(1) According to the type of signal of the maintenance equipment, select the corresponding signal arrester, such as computer network signal arrester, video signal arrester, control signal arrester, antenna feed signal arrester, etc.

(2) According to the operating voltage of the equipment, select the arrester with the appropriate maintenance voltage, such as the operating voltage of the SPD control signal, generally 5V, 12V, 24V.

(3) According to the requirements of the equipment for the insertion loss of the arrester, select the arrester with different bandwidth.

(4) According to the requirements of equipment interface variety, metric system and imperial system, select lightning arresters with different interfaces. For example, BNC: JJ/JK is selected for video signal SPD interface, RJ11 or terminal board is selected for communication line SPD interface.

The above is the knowledge of how to choose DC power arrester signal DC surge protector explained by the editor, hoping to help everyone.
