Single Port PoE Injector with DC Input 48V Compatible with IEEE 802.3af or IEEE802.3at standard

Single Port PoE Injector with DC Input 48V

Model : LNK-PSE48 Series


Overview

The Single Port PoE Injector with DC Input 48V—a specialized Power over Ethernet mid-span device—
features 2x RJ45 ports with clear functional division, tailored for efficient power-data co-transmission. As
a dedicated Single Port PoE Injector with DC Input 48V, one RJ45 port serves as the Ethernet In Port,
designed exclusively for uplink connection to upper-layer network devices like Ethernet switches or routers
to access data signals; the other acts as the PoE Out Port, responsible for simultaneous transmission of
network data and stable PoE power to terminal equipment.
This Single Port PoE Injector with DC Input 48V supports dual power transmission modes to 适配 diverse
device requirements: it can supply power via either the spare line pair (pins 4/5 as V+, 7/8 as V-) or the data
line pair (pins 1/2 as V+, 3/6 as V-), ensuring compatibility with most PoE-powered devices (PDs) without
signal interference. Its 48V DC input design aligns with mainstream industrial-grade DC power supplies and
communication power systems, avoiding the need for additional voltage conversion and enhancing stability
in fixed-power scenarios.
As a high-performance solution, the Single Port PoE Injector with DC Input 48V delivers a simple, economical,
and intelligent Ethernet PoE power supply and data communication experience. It requires no complex software
configuration—users only need to connect the 48V DC input, uplink network, and downstream device to complete
deployment—realizing "plug-and-play" convenience. With low power loss, stable data transmission (supporting 10/
100/1000Mbps adaptive rates), and robust structural design, it meets the demands of superior quality projects.
The Single Port PoE Injector with DC Input 48V stands as an ideal choice for scenarios requiring reliable single-device
power supply, such as standalone 4K IP cameras in security systems, high-bandwidth WiFi 6 access points in offices, or
outdoor IP videophones. Its cost-effective design reduces deployment expenses, while easy installation minimizes on-
site manpower requirements. Whether used in small retail stores, home smart security setups, or industrial edge nodes,
it combines 48V DC input stability, dual-line-pair power flexibility, and single-port precision to offer a trustworthy PoE 
power supply solution.
