The Crestron PWE-4803RU is a professional-grade Power over Ethernet (PoE) injector designed to deliver both data connectivity and electrical power to networked devices over a single Ethernet cable. This unit conforms to the IEEE 802.3at standard (PoE+), providing up to 30 watts of power, which is sufficient for a wide range of powered devices such as VoIP phones, wireless access points, IP cameras, and Crestron's own DM TX transmitters or control system peripherals. The injector simplifies installations by eliminating the need for a separate power outlet and adapter at the device location, reducing cable clutter and enabling more flexible placement of equipment in ceilings, on walls, or in furniture where AC power may not be readily available.

Operation is straightforward: the injector has two Ethernet ports—one labeled "Data In" for connection to a standard network switch and one labeled "Data & Power Out" for connection to the PoE-powered device. It also features an AC power input. The unit takes the data signal from the switch, adds the required DC power to it, and outputs a combined signal on the single output cable. The injector includes protection against over-current and short-circuit conditions to safeguard both the network infrastructure and the connected device. Its metal enclosure is designed for rack-mounting, allowing for neat integration into centralized equipment racks alongside network switches and other AV components.

Designed for reliability in commercial and residential AV/IT installations, the PWE-4803RU operates silently and is built for continuous use. Its standard 1U rack-mountable form factor ensures efficient use of space in equipment closets. By providing a dedicated, high-power PoE source, this injector ensures compliant and stable power delivery, which is critical for the reliable operation of network-dependent systems within a Crestron-controlled environment or any standard IP network.
