Ethernet Network Security Module with Passive PoE Injector, PTF-54-ECO/InPoE/P

The PTF-54-ECO/InPoE/P product is a 4-channel protective module for LAN networks, enhanced with a passive PoE power injector. The maximum power sent to each port is 15W at 48V. By increasing the voltage to 56V, it is possible to transmit power up to 20W. The stated maximum power is due to the simple PoE input (without negotiation circuit) and the 350mA automatic fuse. Passive power transmission above 15W @ 48V is not recommended, as damage to the cable or errors in connections can cause damage to the LAN ports in end devices. For power transmission up to 30W/port, we recommend using the PTF-54-ECO/InPoE/A module, which includes an active PSE negotiation circuit.

The module is designed for building multi-channel surge protection systems for 10Mbit or 100Mbit LAN networks, including protection for computers, switches, PLC controllers, industrial television systems, and other devices installed inside buildings that require PoE power.
It can be used with a LAN switch that does not have PoE ports or 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 48-56VDC power supply with a recommended output of 2A should be used to prevent the power supply from shutting down when the automatic fuse is activated.

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 module.

NOTE! The InPoE module can be connected to a PoE port on a switch, but does not pass PoE power between the LINE and DEVICE sides.

The module has a surge capacity of at least 100A for each LAN wire circuit with direct discharge to ground. Additional equipment includes circuits that protect connected devices from power surges, which can result from induced surge currents during discharge, but also from damage to the PoE power supply. Additional protection against surges is provided by built-in isolating transformers on the LINE and DEVICE sides.

The product is compatible with Ethernet standards 10Base-T and 100Base-TX and can be used with category 5, 5e, 6, and 6a cabling - thanks to the use of shielded sockets, the connection between the LINE and DEVICE sides is not utilized.

The module can be mounted in plastic enclosures PTU/PTF-5-BOX or PTU/PTF-5-BOX/DIN (1 piece) as well as in panels PTU/PTF-5-RACK (up to 4 pieces), creating complete multi-channel protection systems or by using different modules, systems with different purposes and levels of protection.
Modules in Rack panels can be connected with others to achieve an optimal configuration for the required installation needs.

All PTF-54 series grounding point modules are implemented through mounting screws on the Rack enclosure, so any expansion or replacement of the module is very easy and does not require additional actions. The entire device is connected to the ground using the attached cable, attached to a common grounding point.
