LY21-2 series signal SPD is connected in front of equipment in series, is mainly used to
protect against the overvoltage intruded along with the network lines such as network
switch, server,MODEM, network termination equipment and so on.POEnetwork SPD is
applicable for power over Ethernet equipment such as POE camera.
Features
1.Large tolerance to through-current, it adopts multi-level protection.
2.Built-in fast semiconductor protection devices, fast response, low stray capacitance and
low residual voltage.
3.Low insertion loss.
4.POE network lightning protective device uses the network cable to supply power to the
equipment,which is security and cost saving.
