Item Description POE 1000M Network -Protector POE 1000M monitor Camera Surge Protector RJ45 Gigabit Ethernet Protection device Arrester 1000M RJ45 Ethernet Cat5e/6 surge protector with POE support. It simply installs in-line on an RJ45 Cat5e/6 cable. The arrestor has two RJ45 female jacks, so the in-line installation is a very easy and straight forward. It protects any Ethernet devices like switches, routers, laptops/PCs,IP Camera etc from damaging surges caused by- or static electricity. Moreover, because of PoE feature it ALLOWS PoE enabled devices to remain powered while still protected against damaging -strikes or voltage spikes. Material: plastic + metal Color as shown Features Fast energy absorption on over-voltage Low resistance and minimal capacitance - minimal influence on data link Easy in-line installation: two RJ45 female connectors Specification Product Name: Gigabit POE Network -Protector Protection object: POE network switch, POE camera, terminal with POE power supply function Interface: RJ45 Response time Less than 1ns Rated operating voltage: 48V Transfer rate: 1000Mbps Continuous operating voltage: 57V Working temperature: -30 ~ 70 degrees Celsius Operating humidity: 30%-90% Please notes: Two things are crucial and should NOT be missed when using the Ethernet surge protector. Correct positioning: IN jack on the unprotected part of cable and OUT jack on the protected side of cable. Reversed installation will still allow network traffic and operation but there will be no-/surge protection at all! proper grounding: please note the yellow/green ground wire. This wire must be connected to proper electrical ground in the building. Ask a qualified electrician about such grounding or search the Internet for information. Without proper grounding the surge protector will be unable to drain the excess voltage and will be ineffective!
