Material: plastic and 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 percent -90 percent 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 away the excess voltage and will be ineffective! Package Contents: 1 x POE Network -Surge Protection Device Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm. 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. 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. Item Description Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
