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 at 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.
