Protects Power over Ethernet (PoE) equipment 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 5e or Cat 6). This convenient method simplifies wiring while saving the overall cabling cost. 

The LPS® PoE–8/48 is specially designed to provide protection for equipment using 8-wire PoE technology.

The LPS® PoE–8/48 complies with IEEE 802.3 bt Type 4 Standard to protect 4 pairs or 8 wires Cat 5e or Cat 6 cables. They provide protection for all modes against lightning induced surges successfully without impairing the system’s operation or causing excessive in line resistance. These devices are specially designed with high surge capacity to suit even the most lightning prone regions in the world.

 

How it works

The LPS® PoE–8/48 provides unsurpassed performances in lightning surge protection. It deploys multi-stage protection with GDT (Gas Discharge Tube) for primary defence. It is then linked to a second stage surge attenuation component and finally to a voltage dependant device. 

When a transient surge occurs, the LPS® PoE–8/48 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. Under excessive surge conditions, these devices will generally fail in shorted mode to earth to keep the circuit protected.

For more effective protection, we highly recommend that the LPS® PoE–8/48 be installed at both ends of a cable, especially when the connecting equipment is located 30 metres away, in an adjacent building or outdoors. Any SPDs added to the cable will contribute some signal loss. In order to compensate the signal loss, it is recommended to reduce the maximum allowable cable length of the type of signal by 30%. All equipment and SPD earth must be linked to the system’s common earth.
