Surge Protectors is a family of devices suited to protect network and video devices from heavy EM interferences and lightning strikes as well.
They have to be installed mainly when mains cables lie close to signal cables.
SP006-K is designed to protect UTP twisted pair products or any computer equipment against surge high voltage attacks.
SP006P-K is designed to protect PoE (Power over Ethernet) data/communication line in local and wide area network up to 100 BaseT transmission speed, against high voltage surge attacks.
SP007 is a protector suited for any digital video equipment connected by coax cable against high voltage EM attacks.
