1.POE surge protector,Max current:5KA 2.Low electric capacity design, good transmission rate, quick respond.

Brief Introduction 

This signal SPD is suitable for the PoE power supply High Definition Digital Security Camera, PoE power supply Exchanger and Concentrator. This product can prevent the equipment from the permanent damage or wink out caused by induced over-voltage, over current, and other induced surge voltage. RJ45 signal SPD is combined with Intelligent Line Adapter (ILA). When the SPD is used in the PoE system, it can automatically discriminate the idle line power supply from the data line power supply, so that it suitable for any kinds of PoE power supplies system.  

Working Principle

KEJIA Two in One Combined SPD, adopts the discharge currents, limit currents, clamp circuit, voltage stabilization principles to design and manufacture. The SPD will discharge the lightning energy and/or other interference signal into earth as soon as the signal line was intruded by lightning induced over-voltage and over-currents. And it limits the over-voltage and over-currents within the scope that the equipment can bear and keeping normal working status. That makes sure the equipment keep working safely.
