PTF-51-ECO/PoE/Micro, miniature surge protector to ETHERNET, protection of UTP cable, designed to IP cameras LAN switches in the CCTV.
Product discontinued - has been replaced by PTF-51-ECO/PoE/Micro v2
The PTF-51-ECO/PoE/Micro is a miniature surge protector, designed to 100-BaseT LAN networks, based on UTP cable of 5 or 6 category. Small dimensions and built-in RJ-45 jack enables quick and easy assembly and concealment of the device in small housings. Ideally suited for the protection of IP CCTV cameras equipped with mount base. The PT51-51-MICRO protects against the effects of overvoltages and surge discharges, as well as acts of vandalism (stun guns). It can be used to protect LAN inside of buildings, protecting end-line devices and switches or radio bridges. The device individually protects each transmission pair, where the suppression over 6V inside them is eliminated.
A special solution protects LAN devices against voltage increase on PoE power lines in any 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.
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 limiter near the earth of the lightning rod circuit.
