Tupavco Ethernet Surge Protector PoE+ Gigabit 1000Mbs - LAN Network Thunder Lighting Surge Suppressor/Arrester Protection TP302

These surge arrestors seem ridiculously expensive, however speaking from experience of having purchased and examined several different brands and models of surge arrestors, I can say with confidence these are about as well made as you're going to find in this price point and for this type of usage/product. I have adopted extensive use of these (over 2 dozen and counting) on my home network. I have 3 mid-tier managed switches, router, gateway modem, and several unmanaged switches. Probably around 50 end points altogether. I have strategically placed these surge arrestors on my network primarily in order to isolate any potential damage caused by lightning. I learned my lesson a few years ago, when lightning struck my next door neighbor's house. A single CAT5 cable I had near the impact site acted as an antenna. The nearby strong electromagnetic field from the lightning strike was picked up by the CAT5 and fried every piece of equipment it was connected to, until one of my old servers at the time finally gave it enough resistance to stop the damage. I had over $14,000 in damaged equipment. Since then, as I said I've placed these (or similar units I tried before) surge arrestors across my network. Zero issues so far, with the exception of a couple of non-related compatibility issues that I'll discuss below. I live in Texas, and strong, violent thunderstorms are the norm here, especially in spring and summer. If you have not experienced a mid-west thunderstorm, then you will not understand. I moved here from the east coast years ago, and I had no idea they could be so intense until living here. Now, a brief word on compatibility issues. There are some devices that these don't play well with, but that is true with any device like this. These will introduce some additional resistance into your network cable/line, and some devices don't like them. For example, I have a small number of devices connected via SFP+ that even across short distances, when using CAT6 to connect the devices (because the run is too long for DAC's), I have found these devices don't like the surge arrestor between them. It results in erratic data transfer rates. The bottom line is these type of devices are crucial to include within your network design if you want to guard against lightning in particular, and/or any other similar type of electrical discharge risk. They are useful for segmenting your network, and especially to help protect valuable equipment. One word of caution: these devices do require proper setup and implementation. They must be grounded through the included ground wire. This means - contrary to some of the product photos - you can't simply screw them into a wall willy-nilly. Again, some thought is required - or at least prudent - prior to incorporating these (or similar) devices into your home or workspace.

What can you say - it'll work or it won't ! I've lost quite a few bits of gear - over 1000 squids worth - to power surge through the telephone line from nearby lightning strike. Of course this is isn't designed to protect from a direct strike - if the house has exploded it's a sure bet the modem and router have done. But it should protect against induced current from nearby strikes. I wanted something to place between my IDSN modem/router which uses C11 lead from BT socket. This will do it. if I had to niggle the clearance between screw mounts and sockets is a tad tight - esp if you use round-headed screws. For some connecting the earth lead - CRUCIAL TO DO THIS - might prove tricky. The easiest route if you have flush power sockets might be to wire it to a plug - the lead is not long so perhaps crimp an extension. I'm lucky insofar as I have easy access to other options. An alternative is to use one of the screws on the socket faceplate - these SHOULD be earthed. BUT I would check this. These items are not plug-and-play if you are not au fait with things 'lekky'. This bit of kit looks solid and convincing. It at least seems to offer protection - but you won't know, will you. It's insurance that might pay out. Not much else you can do really. There might be a tiny reduction in speed but it's not really noticeable. You won't send this back for construction issues that's all I can say until the next WTF moment when it goes all bright, then dark.

ist die Funktionsfähigkeit weil man dann eine Überspannung erzeugen müsste was man ja nicht möchte. Was mich überzeugt hat ist, das die Absicherung nicht nur einfach über einen dünnen Leiter auf der Platine erfolgt sondern eine Gasentladungsröhre besitzt - hier ist die Hoffnung größer das es im Notfall besser funktioniert. Auch die Verarbeitung ist sehr ordentlich und sauber. Einzig das Kabel für die Erdung könnte länger sein und im Bedarfsfall kürzbar.

Costruzione di classe professionale/industriale. Di percepisce una qualità e una solidità di alto livello. Purtroppo, o meglio per fortuna, questi apparati si possono recensire come eccellenti solo nel caso di fulmini che malauguratamente possano cadere sugli apparati Ethernet protetti da essi. Mi auguro di non dover mai recensire negativamente la qualità dello scaricatore di sovratensione!!!

Une protection toujours utile, on y pense après coup généralement.
