PoE adapter RUIJIE RG-POE-AT30 Gigabit Ethernet, 52 V 31.2 W, 2x RJ-45

The Ruijie Networks RG-POE-AT30 Gigabit Ethernet PoE adapter provides 52 V output and up to 31.2 W of power for devices that require powered Ethernet. This compact inline adapter accepts a wide AC input range of 100–240 V and supplies a stable PoE output over Gigabit-capable RJ-45 connections. With two Ethernet LAN ports and a small footprint, the adapter is intended to add remote power capability where an in-wall injector or powered switch is not available.

Advantages

The adapter delivers Gigabit data throughput while supplying up to 31.2 W at 52 V, enabling simultaneous power and high-speed data transfer over a single Ethernet cable. Its compact black housing and light weight make it easy to place near equipment or inside small enclosures. The wide input voltage range supports international mains supplies, reducing the need for additional power converters. The presence of two RJ-45 ports allows simple pass-through of network traffic while injecting power to the powered device.

Suitable for

• Powering IP cameras and networked surveillance devices
• Supplying PoE access points and wireless devices in small offices
• Providing power to VoIP phones and desktop network equipment
• Adding PoE capability to single-network-drop installations

How to use

Connect the adapter to an AC power outlet using the supplied power cord or compatible cable for the local mains. Plug the network uplink from your switch or router into the adapter’s data input RJ-45 port, then connect the output RJ-45 port to the PoE device that requires power. Verify that the connected device accepts 52 V PoE and monitor device power indicators to confirm successful power delivery. Mount the adapter in a well-ventilated location away from heat sources and moisture.

Recommendations

Use shielded Ethernet cabling and maintain cable lengths within standard Ethernet limits to ensure reliable Gigabit performance. Confirm device power requirements before connection and provide surge or line protection in environments with unstable mains. Avoid placing the adapter in confined spaces without airflow to prevent overheating during sustained operation.
