LY21-2 RJ45 NETWORK SURGE PROTECTIVE DEVICE(POE)

Description：

Product overview
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.POE network SPD is
applicable for power over Ethernet equipment such as POE camera.

The RJ45 POE network SPD protects PoE devices and network equipment from transient surges.
With MOV ZnO inside, it safeguards switches, routers, and IP cameras efficiently.
Encased in PVC/PA66/PBT housing, flame-resistant and compact.
Certified to IEC 61643-11:2011 / EN 61643-11:2022, CE & TUV approved.
As a factory OEM/ODM manufacturer and supplier, we provide wholesale, bulk buy, and in bulk options.
