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

Key specifications

• 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.

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.
