RJ45 Ethernet Network Surge Protector Outdoor Arrester Protection Device for POE Switch Camera SPD Protection Suppressor

DK-nDCt/RJ45 POE Surge Protector Device

1. Introduction

  DK-nDCt/RJ45 POE Surge Protector Device adopts aluminum alloy shell. With features of good appearance, easy installation and convenient wiring, it can long-term work stably under hostile environment.

It is suitable for POE centralized power supply HD digital surveillance cameras, exchanger, concentrator and other POE equipment. It can prevent the equipment from lightning strike or induced over-voltage, over-current or other instantaneous surge voltage.

  It has intelligent circuit recognition function in internal design. When it is used in POE system, it can distinguish free line power supply method and data line power supply, which makes it suitable for all POE power supply system. It has the features of multistage protection, low residual voltage, low capacitance design, good transmission performance, fast response and long life, etc.

2. Technical Parameter

3. Working Circumstance

 1) Working Temperature: -25⁰C~+70⁰C.

 2) Relative Humility: ≤95%.

3) Operating environment: indoor, or somewhere no snow and rain.

4. Installation Instruction

1) It is installed between signal line and protected equipment in series.

2) The input and output connector are both RJ45 connectors. Connect the external line to the side of SPD, and lead to the other side through shielded twisted pair(STP) and unshielded twisted pair which are provided by manufacturer, butt joint with the protected equipment. The connector should be connected firmly.

3) The remark “PE” in the bottom of SPD is grounding wire, which connects the grounding assembled unit and grounding wire. When the grounding wire is connected, tighten the screw. Grounding Wire should be more than 4mm² copper wire, the length of grounding wire should be less than 1 meter but as thick and short as possible, and the ground resistance should be less than 10Ω.

5. Maintenance

  The performance of this product is stable. It doesn’t need special maintenance. To check if it is normal before or after thunderstorm season.  When the system breaks down, change another one.
