Power over Ethernet injector No name SPT-1G/1G-90W-H 90 W single-port PoE injector

The Power over Ethernet injector No name SPT-1G/1G-90W-H is a single-port PoE injector that supplies up to 90 W of DC power to a connected network device while passing data over a single Gigabit Ethernet link. It is intended for installations where existing switches do not provide sufficient PoE power or when only one port requires PoE capability. The unit injects power onto standard Ethernet cabling, enabling deployment of high-power endpoints without replacing network switches or adding power outlets at the device location.

Advantages

This injector delivers a high PoE power budget (up to 90 W) on a single Gigabit port, allowing compatibility with devices that require elevated DC power over Ethernet. The design separates power and data paths, maintaining Gigabit data throughput while supplying power. Its single-port configuration keeps installation simple and cost-effective for targeted upgrades. The compact form factor and standard RJ45 interfaces simplify integration with existing cabling and network equipment.

Suitable for

• High-power wireless access points that require PoE
• IP surveillance cameras with elevated power needs
• Single-board computers and edge devices that accept PoE input
• One-off PoE deployments where a full PoE switch is not justified

Key specifications

• Power output: up to 90 W delivered over Ethernet
• Data interface: single Gigabit Ethernet (10/100/1000 Mbps)
• Ports: one data+power output port and one data input port
• Power injection method: DC power injected onto Ethernet pairs
• Physical interface: RJ45 connector compatibility
• Intended use: in-line PoE injection for standalone port upgrade

How to use

Install the injector between a non-PoE network switch or router and the powered device: connect the network source to the injector's data input port and connect the device to the data+power output port using standard Ethernet cable. Connect the injector to an appropriate AC power source as specified by the manufacturer. Ensure the connected device supports PoE input and that the Ethernet cable is of suitable category for Gigabit performance. Verify link and power indicators (if present) before commissioning the powered device.

Usage recommendations

Use quality Cat5e or Cat6 cabling for reliable Gigabit data and power delivery, and ensure the powered device's PoE class and power requirements do not exceed the injector's 90 W output. For permanent installations, consider ventilation and mounting clearance to avoid overheating and consult device documentation for PoE pinout and voltage compatibility.
