Industrial Gigabit 95W 802.3bt PoE++ Injector (12~48VDC)
Model:LNK-INJ301-90
Overview
The LNK-INJ301-90 is a rugged, industrial-grade Gigabit PoE
injector delivering up to 95W of power for
high-demand devices like cameras and access points. Operating with
a 12~48V DC input, it features a
built-in voltage booster, ensuring reliable power transmission over
100 meters when paired with non-PoE
LAN switches. Both Ethernet ports—one for the switch and the other
for PoE output—support 10/100/1000Base-T
connections and comply with IEEE 802.3ab standards, making this
injector ideal for robust, long-distance power and data solutions.
