LPS® PoE 8 Series
They protect Ethernet signals with 12 V, 24 V or 48 V DC power supply circuits
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.
In the LPS® PoE 8 Series, three devices are specially designed to provide protection for equipment using 8-wire PoE technology. They are each equipped with a built-in AC Power Leakage Filter to prevent the loss of data due to leakage.
Under this Series, the LPS® surge protective devices comply with IEEE 802.3 af Mode / Standard A to protect signal pins 1, 2, 3 and 6 (of Cat 5 or higher) and power pins 4 & 5, 7 & 8 (of 12 V DC, 24 V DC or 48 V DC power supply).
How they work
The LPS® PoE 8 Series devices provide unsurpassed performances in lightning surge protection. They deploy multi-stage protection with GDT (Gas Discharge Tube) for primary defence. They are then linked to a second stage surge attenuate component and finally to a semiconductor voltage dependant device. When a transient surge occurs, the LPS® PoE 8 Series surge protective devices will switch to a fully conductive state to divert high current. They 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 8 Series devices be installed at both ends of a cable, 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.
