PTF-51-PRO/PoE/Micro, high effectivity surge arrester to LAN network, UTP surge arrester, to CCTV solutions based on IP camera.
Product discontinued - has been replaced by PTF-51-PRO/PoE/Micro v2
The PTF-51-PRO/PoE/Micro is a miniature surge arrester, designed to 100-BaseT LAN, based on UTP cables of 5 or 6 category. Small dimensions and built-in cable with RJ-45 plug enables quick and easy assembly and concealment of the device in small housings. Excellent to mount mount in deep base of the IP-CCTV cameras. The surge arregster protects against the overvoltages and surge discharges, as well as acts of vandalism (using of the stun guns). It can be used to protect LAN devices mounted outside of buildings like CCTV cameras radio bridges and LAN switches. The device individually protects each transmission pair, where the overvoltage of over 6V is eliminated inside them and discharges to the ground of loads with values up to 2kA.
A special solution protects LAN devices against voltage increase on PoE power lines in each standards. Lines 4-5 and 7-8 are grouped because LAN 100Base-T uses them only to PoE. The PTF-51-Micro protects PoE against an increase voltage above 58V during surge lighting or during damage to power adapter.
It is recommended for protection of LAN equipment, installed outdoors (walls, attics), where the surge current can be large.
The device does not provide shield continuity for the FTP cable, if such continuity is required, it is necessary to use standard products PTF-51 or PTF-51/DIN.
To ensure an adequate level of protection, it is necessary to connect a good quality grounding or PE protective conductor.
It is not allowed to connect lightning protection circuits and to create a grounding point of the protector near the earth of the lightning rod circuit.
