PoE Injector: PWE-4803RU

Introduction

The PWE-4803RU is a PoE (Power over Ethernet) injector that meets IEEE 802.3af requirements. The PWE-4803RU is designed to power Crestron 802.3af powered devices such as the CEN-WAP-ABG-1G wireless access point. The PWE-4803RU can also power third-party
802.3af powered devices.
NOTE: Only connect this PoE injector to a device that is 802.3af compliant. Plugging this PoE injector into a device that is not 802.3af compliant could damage the device or the PoE injector.
Using the PWE-4803RU, a separate power supply at the location of the 802.3af powered device is not needed. The PWE-4803RU can be mounted at any convenient location up to 328 feet (100 meters) from the device.
