LDY-POE POE surge protector

Application range:

 

LDY-POE series are applied to network device powered by the CAT-5E,which is usually installed at the junction of LPZ1-LPZ3 of lightning protection zone, with function of two classes protection. These series can prevent the network device from damage caused by the overvoltage and overcurrent arising from lightning strike and industrial interference, so they are widely used in the wireless network bridge device.

 

Main Feature:

Modularization DIN rail design, convenient for installation and replacement;Build-in temperature control circuit breaker, high security performance; Green light in notice window indicates normal; red indicates broken, replacement notice, which is clear and easy distinguished;Function of multilayer protection: power system and network signal system;Build-in elevating earthing terminal, more reliable earthing.

Installment instruction:

Series connection, connection at the input front side of protected device. Connect the lightning earthing wire to the lightning grounding network in the computer room, make sure the earthing reliable and the earthing line less than 0.5m Free maintenance, green light constant on indicate normal at 48V, off indicate broken, and then dismantle the protector and check the input power status. If the input power is normal, the protector is broken and need being replaced. If the signal is inaccessible, dismantle the product and check it again. If recover after dismantlement, the signal section is broken, the protector should be replaced immediately.
