PTF-1-ECO/PoE is a universal protection dedicated to computer and telephone twisted pair, protects from effects of surge and lightning. It can by uses in systems of local LAN network to protection of overhead lines between buildings, protection of active systems of Video signal transmission by computer twisted pair and telephone lines. The device has individually protection of each core of cable, where after crossing voltage above 90V, followed short circuit its to ground. By using innovative components PTF-1-ECO/PoE Protection has very low capacity and high reaction speed, which have negligible effect on high-frequency signals transmitted, very short reaction time and ability to multiple response.

Construction was constructed very carefull to avoid occurrence of crosstalk between channels and introduction delays between individual cores. This is important for high-frequency systems, inter alia of LAN network of 5 category.

All pair are protected, inclusive with cable, which are using to PoE supply.

For correct operation is needed connecting a ground cable. For this purpose should be used a probe embedded into the ground, which is located as close as possible of surge protection. In any case, do not connect to protection cable of electrical installations or to existing installation of lightning.

Simplified block diagram

Because discharge may occur on either side, a road transmitted by load can take a long time. To increase effectiveness of protection is recommended to use surge protections at both ends of cable.
