Protect your transmission of Ethernet signals with 48 V DC power supply circuits against lightning induced surges

PoE (Power over Ethernet) technology is fast gaining popularity because it  simultaneously transmits data as well as supply DC power by simply using Ethernet cables (Cat 5 or higher). This convenient method simplifies wiring while saving the overall cabling cost. 

The LPS® PoE 4/48 is specially designed to provide protection for equipment using 4-wire PoE technology. 

This LPS® surge protective device complies with IEEE 802.3 af Mode / Standard A to protect signal pins 1, 2, 3 and 6 (4 wires) of Cat 5 or higher cable with 48 V DC power supply.

How they work

The LPS® PoE 4/48 device provides unsurpassed performances in lightning surge protection. When a transient surge occurs, the LPS® PoE 4/48 surge protective device will switch to a fully conductive state to divert high current. It will then reset automatically to a non-conducting state when the current falls below the holding current.

For more effective protection, we highly recommend that the LPS® PoE 4/48 device be installed near the equipment, especially when the connecting equipment is located 30 metres away, in an adjacent building or outdoors. The cable should not exceed 75 metres for optimal performance. All equipment and SPD earth must be linked to the system’s common earth.
