ComNet CWPOEIPS-15 is a low-cost power over Ethernet (PoE) midspan injection module that injects 48 VDC at 0.3 amperes to the unused pairs of any UTP or STP CAT-3, CAT-4, or CAT-5 network cable. Operating power and 10/100TX Ethernet data are easily combined on one cable, eliminating the need to install additional power outlets and electrical cabling. Housed in a compact, rugged, light-weight package, and utilizing a completely self-contained 100 to 240 VAC input power supply, the CWPOEIPS is fully compliant with the requirements of IEEE 802.3af for Power Sourcing Equipment (PSE), and features auto-detection of powered devices (PDs). Transmission distances of up to 100 meters are supported, and this injector supplies operating power for all PDs drawing a maximum of 15.4W. The unit provides AC line and powered device over-voltage and short circuit protection. Ideally suited to fiber optic, wireless, or other networks where it may be difficult to furnish operating power to the PDs, the CWPOEIPS is a true plug-and-play product requiring no user configuration or other set-up. The unit is designed for deployment in benign/conditioned 0 to +45 degree C operating environments.
