PoE adapter Trendnet TPE-147GI

The TRENDnet TPE-147GI is a 4-port Gigabit PoE+ injector that adds Power over Ethernet to a non-PoE Gigabit switch. It provides gigabit data connectivity and delivers power to up to four PoE or PoE+ devices, supporting IEEE 802.3af and 802.3at standards. The compact, fanless unit connects to a switch via four data-in ports and supplies data+power over four PoE output ports, with cable runs supported up to 100 m (328 ft.).

Advantages

The injector supplies up to 30 W of power per port for PoE and PoE+ devices while preserving gigabit data throughput. Its fanless design eliminates operating noise and reduces energy consumption. The device requires no configuration—connect the non-PoE switch to the data-in ports and plug PoE devices into the data+PoE out ports for immediate operation.

Suitable for

• Powering IP cameras at remote locations up to 100 m from the switch
• Supplying PoE access points where the existing switch lacks PoE
• Connecting VoIP phones or other PoE devices without replacing the switch
• Small office or retail deployments requiring up to four powered Gigabit links

• PoE standards supported: IEEE 802.3af and IEEE 802.3at (PoE+)
• Power per port: up to 30 W
• Ports: 4 × Gigabit data-in (RJ‑45), 4 × Gigabit data+PoE out (RJ‑45)
• Maximum cable distance for PoE: 100 m (328 ft.)
• Dimensions: 126.4 × 74 × 32 mm
• Weight: 0.322 kg
• Color: Black
• Input voltage: 100–240 V

How to use

Connect the four gigabit data-in ports of the injector to a non-PoE Gigabit switch using standard Ethernet cables. Plug PoE or PoE+ devices into the corresponding data+PoE output ports. Ensure cable runs do not exceed 100 m for each connection. Power the injector from an AC outlet within the specified 100–240 V range; no additional configuration is required for basic operation.

Usage recommendations

To maintain stable power delivery, calculate combined power requirements of connected devices so the total does not exceed the injector’s rated output; use shielded or high-quality Cat5e/Cat6 cables for best performance and keep runs within the 100 m limit.
