LAN Network Surge Protector Series EXT, PTF-51-EXT/PoE/T with Heat-Shrink Cover

Surge protector, designed to protect one LAN line from the effects of surges and atmospheric discharges. It is compatible with Ethernet networks of 10Base-T and 100Base-T standards, used in connections with PC computers, CCTV system cameras, industrial automation devices and buildings, as well as other consumer devices. It includes direct grounding of large shock loads individually from each wire, without commonly used intermediary elements that weaken shock resistance and have a huge impact on the emission or absorption of electromagnetic interference.

Three levels of protection in the data line using MOSFET technology, effectively protect delicate circuits of network interfaces and introduce an additional separating buffer in case of large potentials between the LAN switch and individual end points. In addition, MOSFET technology lowers the potential level that reaches the protected device (Voltage protection level UP) during a surge to a value that is only slightly higher than the rated operating voltage (Un).

Built-in PoE protection circuits eliminate voltage surges between transmission pairs 1,2 - 3,6 and pairs 4,5 - 7,8, which are used exclusively for PoE power supply in 100Mbit networks. They are grouped together to simplify the protective circuit and one pair is treated as one circuit line. PoE protection circuits protect LAN end devices from damage caused by atmospheric discharges or uncontrolled voltage surges, for example due to PoE power supply failure. The solutions used are completely neutral for each PoE standard and protect each of them, including Hi PoE.

PTF-51-EXT/PoE/T is designed for installation near LAN end points such as: PC computers, PLC controllers, IPC cameras, radio transmitters, and Internet of Things devices. Proper grounding using a PE line is necessary for correct operation, preferably from the shortest, dedicated grounding point. It is important to follow the directional operation of the protective function described in the user manual and not reverse the device connections in the LAN installation, which may cause improper operation or even damage.

The PTF-51-EXT/PoE/T ensures continuity of the FTP cable screen between the input and output, and also discharges the charge that appears between the screen and the ground. As it is recommended to ground the FTP cable screen only on one side, the screen on the protector side is galvanically separated at 90VDC during normal operation.

To protect one LAN channel, two single-channel protectors can be used, installed at both ends of the cable and properly grounded. In case of the need to protect multiple LAN circuits, it is recommended to use a multi-channel limiter on the LAN switch side and single-channel limiters on the end devices side.

If the external IP cameras are protected with the EXT series protector, a multi-channel protector of at least the PRO series must be used on the LAN switch side, otherwise the protection of the LAN switch will be insufficient.

If the EXT series protectors are connected to the LAN patch panel, it must be based on Keystone connectors. Standard patch panels with LSA (Krone) sockets have too low impact strength of printed circuits and may be damaged.

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