12~48V DC Power Input Industrial Gigabit PoE+ Injector


Model :  LNK-INJ301


Overview

The LNK-INJ301 is a specialized 12~48V DC Power Input Industrial Gigabit PoE+ Injector—a hardened
PoE solution engineered for industrial-grade reliability and high-power device compatibility. As a dedicated 
12~48V DC Power Input Industrial Gigabit PoE+ Injector, it enables seamless connection between IEEE
802.3af/at PoE-powered devices (PDs) (such as high-definition surveillance cameras, enterprise-grade
wireless access points, and industrial IoT sensors) and non-PoE LAN switches, supporting stable power-
data co-transmission over distances up to 100 meters—ideal for harsh industrial environments where
standard injectors may fail.
A core advantage of the 12~48V DC Power Input Industrial Gigabit PoE+ Injector lies in its dual-port gigabit
performance: both the Ethernet uplink port (for connecting to non-PoE switches) and the PoE Out downlink
port (for linking to PDs) support 10/100/1000Base-T transmission and comply with IEEE 802.3ab gigabit
Ethernet standards, ensuring unimpeded high-bandwidth data flow even when powering energy-intensive
devices. The PoE Out port further adheres to IEEE 802.3at (PoE+) standards, delivering up to 30W of power
to compatible PDs—sufficient for mid-power industrial equipment that requires consistent power supply.
Designed for industrial scenarios with fluctuating power conditions, the 12~48V DC Power Input Industrial
Gigabit PoE+ Injector features a 12~48V DC wide-range power input, making it adaptable to diverse industrial
power systems (such as battery backups, industrial power supplies, and distributed DC grids). This wide-voltage
design eliminates the need for additional voltage converters, reducing deployment complexity and enhancing
reliability in high-availability applications (e.g., factory automation lines, outdoor industrial monitoring, and
remote oil/gas sensing stations). Its hardened construction—including anti-vibration, anti-electromagnetic
interference (EMI), and wide operating temperature range (typically -40℃ to 75℃, suitable for extreme
industrial environments)—ensures stable operation in harsh conditions where standard commercial injectors
would malfunction.
The 12~48V DC Power Input Industrial Gigabit PoE+ Injector provides an integrated, low-maintenance power
solution for industrial networks: it requires no complex software configuration, supporting plug-and-play
deployment—simply connect the uplink port to a non-PoE gigabit switch, the downlink port to the target
PoE+ device, and the DC input to a compatible power source. Built-in overcurrent, overvoltage, and short-
circuit protection mechanisms further safeguard both the injector and connected industrial devices, preventing
damage from power anomalies. With its industrial-grade durability, 12~48V wide DC input, and gigabit PoE+
capabilities, it becomes a trusted solution for upgrading industrial non-PoE networks to support high-performance, 
power-hungry devices.
