Ruijie POE-AT30 802.11at PoE+ Power-over-Ethernet Injector

The Ruijie 108-RG-POE-AT30 is a compact power-over-Ethernet injector designed to feed up to 31.2 watts of 48 Vdc PoE+ into a single network link, making it ideal for higher-power devices such as Wi-Fi access points, PTZ security cameras or VoIP phones. It sits inline between an AC power source (100–240 V) and your LAN connection, delivering both data and power over a standard RJ45 cable. With an operating window from –10 °C to 45 °C and a footprint under 100 × 52 × 33 mm, it suits a range of indoor installations where space is tight but reliable PoE+ is essential.

Although only one model is commonly stocked, the AT30 series can be found in variations that differ by output power and connector configuration to match different device requirements. This particular SKU follows the 802.11at PoE+ specification, ensuring compatibility with most modern PoE equipment while offering surge protection and simple plug-and-play deployment. Network integrators, small businesses and managed service providers will find it a straightforward way to upgrade existing switches without PoE capabilities or to extend power to remote network endpoints.
