Industrial Gigabit PoE+ Injector StarTech POEINJ30W — 30W 802.3at Midspan, 48–56VDC, DIN-rail, -40°C to +75°C

The StarTech POEINJ30W is an industrial Gigabit PoE+ injector that delivers up to 30 W of power to IEEE 802.3af/at powered devices over a single Ethernet cable. Designed as a midspan injector, it supports 10/100/1000 Mbps data rates and accepts 48–56 VDC input. The unit is built for harsh environments with an operating temperature range from -40°C to +75°C, IP-30 rated aluminum housing, and proven resistance to vibration, shock, and free-fall. DIN-rail mounting and dual power inputs allow flexible installation and redundant power arrangements for continued operation in industrial and outdoor-adjacent deployments.

Advantages

The injector supplies both power and Gigabit data on the same Cat5e-or-higher cable and is compatible with PoE and PoE+ devices up to 30 W. Industrial-grade construction and a wide operating temperature range make it suitable for demanding sites. Dual power input options (terminal block and coaxial with barrel plug adapter) enable redundancy and simplified connection to local power systems. The compact, black aluminum housing and DIN-rail form factor save space in control cabinets or enclosures.

Suitable for

• Powering network cameras at remote or industrial locations
• Supplying sensors and monitoring devices that require up to 30 W
• Providing PoE power to Wi‑Fi access points in industrial or commercial spaces
• Midspan installations where existing network switches do not provide PoE

How to use

Mount the injector on a DIN rail inside an appropriate enclosure or cabinet. Connect a suitable 48–56 VDC power source to the injector using the terminal block or the coaxial input with the included barrel plug adapter; ensure the power source and wiring meet local electrical codes. Link the injector’s data input to a non-PoE network switch or router using Cat5e or higher cabling. Connect the PoE output to the powered device (camera, sensor, or access point) with a Cat5e-or-higher Ethernet cable, observing the maximum 100 m cable run for both power and data. Verify link/activity LEDs and confirm the powered device receives the expected power and network connectivity.

Usage recommendations

Use shielded or properly rated Ethernet cabling in electrically noisy or outdoor-adjacent environments, and keep total cable length under 100 m to maintain reliable power delivery. For redundancy, connect two independent DC power sources to the dual inputs. Ensure the powered device’s maximum power draw is within the 30 W budget and follow manufacturer instructions for both the injector and the PD when integrating into industrial installations.
