12~48V DC Input Power over Ethernet Industrial Gigabit PoE+ Injector
Overview
The LNK-INJ301-30 is a ruggedized Gigabit High Power PoE Injector designed to power
IEEE 802.3af/at PoE devices, such as cameras and access points, from a non-PoE LAN
switch within a 100-meter range. Both the Ethernet port (to connect to the switch) and the
PoE output port (to power PoE devices) support 10/100/1000Base-T speeds and comply
with IEEE 802.3ab and 802.3at standards. This PoE injector offers a flexible power
solution, with an input voltage range of 12-48VDC, making it ideal for high-availability
applications in harsh environments.
