8-channel surge arrester for LAN Gigabit Ethernet, PTF-68R-EXT / PoE

8-channel surge protector dedicated for Gigabit Ethernet networks, based on category 5, 5e, 6, and 6a structured cabling. It is built from two PTF-64-EXT modules, mounted to the PTU/PTF-6-RACK base. It is installed in a 19" Rack cabinet on the front rail, allowing easy switching of cables in user networks or on the rear rail using LK-MOUNT angled brackets, in case of application for IP-CCTV recorders.

The front RJ-45 (DEVICE) sockets represent the surge-protected side and are connected to the LAN switch ports. The sockets located at the back represent the unprotected side (LINE), to which long lines of LAN infrastructure are connected. When using the PTF series surge protector, an additional patch panel with RJ-45 sockets is usually used. To ensure continuity of shielding for FTP cables, shielded patch cords should be used. The placement of the unprotected side sockets at the back of the surge protector is conditioned by the need to ensure high quality of its transmission parameters and low crosstalk.

The PTF-64 series modules are devices of very high quality in terms of surge protection as well as transmission. The use of multilayer PCB boards and modern components in MOSFET technology has resulted in compliance with the category 6 cabling standard and correct tests for frequencies of 4x250MHz.

The components used in MOSFET technology significantly reduce the level of voltage protection (Up) to a value slightly higher than the rated operating voltage (Un). The voltage pulse reaching the protected device during a surge or discharge is even several times lower than in the case of a standard solution without the use of MOSFET technology. The risk of breakdown of the insulation of isolating transformers in network cards due to potential differences between locally grounded or locally powered LAN devices is also reduced.

Independent PoE protection protects against voltage spikes between pairs 1,2 - 3,6 and 4,5 - 7,8. This protects the power supplies of LAN end devices from damage due to surges caused by lightning strikes or uncontrolled voltage increases, for example, due to a failure of the PoE power supply. The solutions used protect all types of PoE power and allow power transmission in the Hi PoE standard.

The panel has additional space to mount 2 PTF-64 or PTU-64 modules, allowing the surge protector to be expanded at any time, up to a maximum of 16 channels. Proper grounding of the surge protector should be ensured by connecting the included grounding wire to a properly grounded Rack cabinet. The optional PTU/PTF-5/6-COVER provides protection for the circuits and connections of the surge protector against dust, and also serves as an additional shield against interference when a large number of panels are present.

The best level of protection is achieved by using surge protectors on both sides of the cables: Multi-channel on the LAN switch side and single ones on the end device side, for example, PTF-61-EXT/PoE.

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