8-channel surge protector with active PoE input, PTU-58R-ECO/InPoE/A

8-channel surge protector, dedicated to protecting 100Mbit LAN networks, protecting PC computers, industrial automation systems and building automation, as well as IP-CCTV industrial television installations from surges. It provides protection for data transmission paths and supplies PoE power up to 30W/channel in active mode. The active PSE negotiation system monitors the power status and consumption, ensuring full safety of the installation and connected LAN devices. It protects against damage in case of connection errors, wire shorts or failure to comply with the receiver standard. The product provides PoE power according to IEEE 802.3af/at specification, option A.

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 inside the device. Built-in PoE power protection protects against power surges or power supply failures.

This product can be used with a LAN switch that does not have PoE ports or can be 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 should be used, providing sufficient power for the powered devices - a recommended power supply should have a power of about 150W.

The effectiveness of surge protection is 100A in an 8/20µs impulse on each wire, which is sufficient for most indoor applications, where the main cause of damage may be the induction of an electromagnetic impulse in the wires.

The protective panel consists of two PTU-54-ECO/InPoE/A 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.

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 connecting and servicing. It can be connected to existing patch panels with LSA (Krone) connectors using RJ-45 patch cords. The optional PTU/PTF-5/6-COVER cover protects against dust and accidental damage to modules, and special holes in the base allow the panel to be mounted on a wall. 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 on the end devices side.
