Product discontinued - has been replaced by PTF-51-ECO/PoE


PTF-1-EXT/PoE is a high-efficiency surge protection for 100Mbit Ethernet and IP CCTV cameras. In series Extreme using the latest solution in the form of super fast fuse MOSFET. It protects from effects of surge and lightning and vandalism (effect of stun guns). It may be using in systems of local LAN network to protection of overhead lines between buildings, to protects connections between switches for cable of 6 category. The device has individually protection of each transmission pair, where after crossing voltage above 90V, followed short circuit its to ground. 4, 5 and 7, 8 cables are connected together, to increase current flowing for a PoE standard (Power over Ethernet). By using innovative components PTF-1-EXT/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.

Built-in automatic fuses protects PoE power supply from damage, in event of short circuit at power supply of receiving device. Also built-in LEDs, signaling presence of power supply entering and exiting from PTF-1 protection.

Construction of circuit is completely shielded from bottom and from top, which provides high immunity to electromagnetic interference and continuity of screen between input and output. Screen has independent circuit protection, so that it is not permanently connections with ground. This is important for risk of potential differences and appearing of parasitic signals.

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.
