Ethernet surge protector DIY

October 28, 2008, 11:04 PM
For people, who have skills to assemble that. If you dont have, find friend who can do that.

Instead of many diodes D1-D7, you can use DB107.

Dont forget, you need PROPER, GOOD grounding. Dont use "zero" wire in your sockets, water pipes and etc.

Here is also schematics of simple "UPS" for switch, or broadband router or wireless. Sure parts will vary, depends on required voltage.


If you dont have protection, better unplug your appliances from sockets, and ethernet network during the lightenings.
