Crestron part number PWE-4803RU
The Crestron PWE-4803RU is a PoE injector, an 802.3af compliant Power over Ethernet source for PoE powered devices. It puts power and data onto one CAT5/6 network cable, so the device at the far end does not need its own power supply where it is mounted.

About the Crestron PWE-4803RU
Power over Ethernet is a standards-based way of running an Ethernet device from a single cable. The PWE-4803RU adds 802.3af power to the network connection for a PoE powered device, so data and power travel together on the same CAT5/6 run. This removes the need to fit a separate power supply at the device location, which keeps the wiring at that end to one cable.
Crestron notes that the injector can be mounted at any convenient location, so it does not have to sit beside the device it powers. When replacing a failed unit, check the part number on the old injector and confirm that the connected device is an 802.3af PoE powered device. This page covers the single PWE-4803RU part number.

Questions about the Crestron PWE-4803RU
What is the Crestron PWE-4803RU?
It is a PoE injector: an 802.3af compliant Power over Ethernet power source designed to support PoE powered devices. It delivers power and data together over a single CAT5/6 network cable, so the powered device does not need a separate power supply at its location.
Which PoE standard does the PWE-4803RU support?
Crestron describes the PWE-4803RU as 802.3af compliant. Check that the device you want to power accepts 802.3af Power over Ethernet, and if you are replacing an existing injector, match the part number printed on the old unit.
What cable does the PWE-4803RU use?
It works over a standard CAT5/6 network cable. The same cable carries the Ethernet data and the power for the connected device, which Crestron describes as a one-wire solution, so no second cable or local power supply is needed at the device end.
Where can the injector be mounted?
Crestron says the PWE-4803RU can be mounted at any convenient location. Because the power travels along the network cable, the injector does not need to sit next to the device it powers, and no separate power supply is needed where that device is fitted.
What kind of devices can it power?
It is designed to support PoE powered devices, meaning Ethernet devices that take their operating power from the network cable. As it is 802.3af compliant, it suits devices that accept 802.3af PoE. Check the power needs of the device before choosing this injector.
How much is the Crestron PWE-4803RU?
Crestron asks its dealers to give the price of the PWE-4803RU directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the PWE-4803RU?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the PWE-4803RU on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the PWE-4803RU come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the PWE-4803RU develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the PWE-4803RU in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Yes. We supply Crestron to end users, with or without installation. If you are not sure it suits your system, send us the part numbers you already have and we will check.
