The PTF-54-PRO series surge protector modules are new devices with increased strength for high surge currents. Direct discharge of large currents without intermediate elements (looping through LAN transformers or coupling by diode bridges) and other solutions reducing their price. They provide a total protection at the level of 14kA for the FTP cable.

They have improved transmission and strength parameters for long-term currents. Tuned differential pairs and better quality RJ-45 sockets provide less crosstalk and suppression of transmission lines, and new solutions and components provide correct operation and protection of PoE up to 60W (HiPoE).

On the basis of PTF-54-PRO/PoE modules, you can build 10Mbit or 100Mbit LAN surge protection systems, they serve to protect computers, switches, PLCs, CCTV systems and other devices installed inside or outside buildings.

Additional equipment are circuits that protect devices powered by passive or active PoE standards, where damage can arise as a result of induced surge currents during atmospheric discharge, but also as a result of damage to the PoE power supply. The PTF-54 series modules cooperate with PoE power supply in many IEEE standards, including: 802.3af, 802.3at and 802.3bt - type 3 (HiPoE, UPOE).

It is compatible with 10Base-T and 100Base-TX Ethernet networks and can be used with 5, 5e and 6th category cabling and shielded sockets ensures full continuation of the FTP cable shield. Because in this type of networks, 4.5 and 7.8 steam are used only for PoE supply, they have been grouped, so the module shouldn't be an element taking part in the measurement of cabling parameters.

The module can be mounted in PTF-5-BOX plastic housings (1 pc) or in the PTU/PTF-5-RACK panels (up to 4 pcs), creating complete multi-channel surge protection systems. With the use of various modules, we obtain mixed systems with various purposes and a protective level.

All modules of the PTF-54 series are grounded by the mounting screws of the rack panel, therefore the possible expansion or replacement of the module is very easy and requires no additional steps. The connection of the entire device to the earth is made with the aid of an attached cable, fastened to a common earthing point.

Protected side and unprotected side are equipped with RJ-45 sockets, therefore modules can be combined with other patch panels that terminate LAN cables. However, standard patch panels with LSA connectors (Krone) should not be used, as the strength of their printed circuits for high surge currents is very low and at the moment of the surge discharge is a risk that they will be damaged. As endings of the LAN line, only patch panels with Keystone type connectors should be used.
