8-channel surge protector with passive PoE power function, PTF-58R-ECO/InPoE/P

8-channel surge protector, dedicated to protect 100Mbit LAN networks, PC computers, industrial and building automation systems, and IP-CCTV industrial television installations. It provides protection for data transmission paths and delivers PoE power up to 15W/channel in passive mode. The protection effectiveness is 100A in 8/20µs impulse for each wire, which is sufficient for most applications inside buildings, where the main cause of damage can be electromagnetic impulse induction in wires.

By increasing the supply voltage to 56V, it is possible to transmit up to 20W per channel. The maximum power given is dictated by simple PoE input (without negotiation circuit) and 350mA automatic fuse. Passive power transmission above 15W @ 48V is not recommended, as wire damage or connection error can cause damage to LAN ports in end devices. For power transmission up to 30W/port, we recommend using the PTF-58R-ECO/InPoE/A module, which includes an active PSE negotiation circuit.

The protector consists of two PTF-54-ECO/InPoE/P modules, mounted in a PTU/PTF-5-RACK housing and can be easily expanded to 16 channels using any PTU-54 or PTF-54 modules.

PoE transmission takes place on transmission lines 1-2, 3-6, similar to the IEEE standard: 802.3af, option A. Pairs 4-5 and -7-8 are completely disabled within the device. Built-in PoE power protection protects against power surges or damage to the power supply.

The product can be used with a LAN switch that does not have PoE ports or is used to increase the number of PoE ports, in case of insufficient power or number of PoE ports in the LAN switch. To power each module, a power supply with a voltage of 48-56VDC and a recommended output of 2A should be used to prevent the power supply from shutting down when the automatic fuse is activated.

The panel is equipped with RJ-45 sockets on the protected side and on the unprotected side. This facilitates adaptation to existing systems and speeds up the process of connection and servicing. It can be connected to existing patch panels with LSA (Krone) connectors using RJ-45 patch cords. The optional cover PTU/PTF-5/6-COVER protects against dust and accidental damage to modules, and special holes in the base allow the panel to be mounted on the wall as well. Signal cables can be mechanically secured against pulling out using cable ties, using holes or protrusions on the back of the panel.

In the case of use in CCTV installations with IP recorders, the panel can be mounted on corner brackets at the back of the Rack cabinet. The benefits of this solution include: more space in the cabinet, convenient access to all connections, and shorter patch cords - IP recorders usually have all connectors at the back.

The best protection efficiency is achieved by using surge protectors at both ends of the LAN cable and proper grounding. Usually, a multi-channel device is used on the LAN switch side, and a single-channel protection is used on the end devices side.
