12~48VDC Power Input Industrial Gigabit PoE+ Injector


Model: LNK-INJ301 Series



LNK-INJ301 is a Hardened Gigabit High Power PoE Injector. It allows you to connect the IEEE 802.3 af/at PoE device such as camera and access point with a non PoE LAN switch within the distance of 100m. Both of the Ethernet port (to switch) and the PoE Out port (to PoE device) support 10/100/1000Base-T and are compliant with IEEE 802.3af. The PoE Out port is also compliant with IEEE 802.3 at.


LNK-INJ301 provides an integrated power solution with a wide range voltage of 12~48VDC for high availability applications.
