Serial Port Signal Surge Protector 9 Pin Lightning Arrester Low Output Residual Pressure

Serial port lightning protector, DB9 signal lightning protector, surge protector, 9 pin lightning arrester

Brief introduction

    DB serial signal protector is designed according to the standard of IEC and GB. It is widely used in the surge protection of DB09 serial communication system in industrial control, telecommunication, local area network and commercial and military fields. The grounding cable can be grounded through the DB type serial port metal casing, and the grounding path is as short as possible, and the length is not more than 1.5 meters. It is mainly applied to the serial protection of electronic devices in RS232, RS422 and RS485 systems.

Product specification

  1. Working voltage:24V

  2. Max continuous operating voltage(UC):30V

  3. Voltage protective level(UP):<60V

  4. Nominal discharge current(IN):10KA

  5. Response time(NS): ≤10

  6. Characteristic impedance: 75Ω

  7. Insertion loss: ≤0.1dB

Working principle of product

    The product is built with a fast transient voltage suppression protector designed to protect the RS interface and use a TVS transient voltage suppressor. Under normal circumstances, the TVS tube is in a high voltage resistance state. When the ends of the TVS tube are subjected to instantaneous high energy shock, it can reduce the impedance of the two end at a high speed and absorb a large current at a higher speed. The voltage at both ends is clamped to a predetermined value, so that the circuit elements behind it will not be damaged by transient high voltage impact.

Product features

  1. easy and easy to install and use

  2. fast reaction speed

  3. low output residual pressure and superior transmission performance

  4. volume, easy to carry and strong adaptability

Use of attention

  1. the length of the ground path should not exceed 1.5 meters

  2. before a series of surge protectors are connected to the protected equipment, they must turn off the power supply, and no live operation is strictly prohibited.

  3. the series connection is installed between the lines of the protected equipment, the interface links must be reliable, and the input and output markup on the surge protector. The output terminal is connected to the protected device.

  4. the grounding wire must be connected with the power supply protection system reliably.
