Προσαρμογέας PoE Trendnet TI-IG290

The TRENDnet TI-IG290 PoE adapter is a 2-port industrial 2.5G PoE++ injector that adds Power-over-Ethernet to non-PoE 2.5G switches. It supports multi-rate Ethernet at 10/100/1000/2500 Mbps and supplies up to 95 W to two connected PoE devices, with a total PoE budget of 180 W. The unit features a fanless design, an IP30-rated metal enclosure, and operates over a wide industrial temperature range of -40° to 70° C, making it suitable for harsh environments.

Advantages

The TI-IG290 provides dual 2.5G PoE++ outputs while remaining compact and fanless to reduce noise and power loss. Its IP30 metal housing and high MTBF ensure durability and continuous operation under vibration, shock, and extreme temperatures. The injector supports common PoE standards (including IEEE 802.3af and 802.3at) and multi-rate Ethernet for compatibility with a range of network devices.

Suitable for

• Adding PoE/PoE++ power to a non-PoE 2.5G switch
• Powering two PoE network devices up to 100 m away (328 ft.)
• Industrial and harsh-environment network deployments
• Surveillance cameras, access points, and industrial IoT devices

How to use

Connect the TI-IG290 injector to a non-PoE 2.5G switch using an Ethernet cable on the data input port, then connect up to two powered devices (PDs) to the injector’s PoE output ports. Run Cat5e/Cat6 cables up to 100 meters (328 ft.) between the injector and each PoE device. Ensure the switch and connected devices support the specified data rates, and verify the total power draw of connected devices does not exceed the injector’s 180 W budget.

Recommendations

Install the injector in a well-ventilated, dry location and secure it to a stable surface to minimize vibration. For reliable PoE delivery use quality Ethernet cables (Cat5e or higher) and confirm device power requirements before deployment to avoid exceeding the total PoE budget.
