8-channel LAN Gigabit Ethernet protection, PTU-68R-PRO/PoE

8-channel protection for Gigabit Ethernet networks, based on category 5, 5e, 6, and 6a cables. It is built with two PTU-64-PRO modules, mounted in a PTU/PTF-6-RACK housing. It is designed to be installed in a 19" Rack cabinet on the front rail for standard use, or on the rear rail using angled LK-MOUNT brackets for use with IP-CCTV recorders - many IP recorders have a built-in switch with ports on the back.

The front RJ-45 sockets (DEVICE) serve as the protected side against surges and are connected to the Gigabit Ethernet LAN switch ports using patch cords. The rear LSA connectors serve as the unprotected side (LINE), to which long lines of LAN network infrastructure are connected without using RJ-45 connectors. This solution creates two devices in one: a patch panel for terminating transmission lines and effective surge protection. This simplifies installation and reduces the number of additional elements, resulting in cost savings. To ensure continuity of the FTP cable shield, shielded patch cords should be used and metal clamps equipped with electronic plates should be used.

The PTU-64-PRO series modules are devices of very high quality for surge and transmission protection. The use of multilayer PCB boards has resulted in compliance with the category 6 cabling standard and successful tests for frequencies of 4 x 250MHz.

The independent PoE protection circuit protects against voltage surges between pairs 1,2 - 3,6 and 4,5 - 7,8. This protects LAN end device power supplies from damage caused by surges, such as those caused by lightning strikes or uncontrolled voltage increases, for example when a PoE power supply is damaged. The solutions used protect all types of PoE power supplies and allow for power transmission in the Hi PoE standard.

The protection panel has additional space for mounting 2 PTF-64 or PTU-64 series modules, which allows for expansion to a maximum of 16 channels at any time. Proper grounding of the LAN protection must be ensured by connecting the included cable to a properly grounded rack. The optional PTU/PTF-5/6-COVER cover provides protection for circuits and protection connectors against dust, and also serves as additional protection against interference when there are a large number of panels.

The best level of protection is achieved by using security measures on both sides of the cables: Multi-channel on the LAN switch side and single on the end devices side, for example PTF-61-PRO/PoE.

Product tested according to categories D1, C2, C1, B2. It is intended for use at the boundaries of LPZ0/LPZ1 zones or higher.
