Maintain power to the devices that keep your network and AV stack connected. The Eaton AV550SC delivers 550 VA / 300 W of standby backup in a compact tower footprint, giving structured wiring enclosures a dedicated layer of protection against outages, surges, and EMI/RFI noise. It is designed for the equipment that often gets overlooked until it fails: modems, routers, RF amplifiers, network interfaces, cameras, and modulators. With 10 minutes of runtime at half load and 3 minutes at full load, this unit gives you enough time to ride through brief interruptions or complete a controlled shutdown. The tower design fits cleanly into residential or light commercial wiring spaces where rack hardware is not practical. For installations carrying voice, internet, coax, and audio/video distribution, the AV550SC helps preserve uptime and signal quality without adding complexity. This is the right choice when the cost of a dropped connection is higher than the cost of protection. It combines battery backup, surge suppression, and line conditioning in one enclosure-focused UPS built for always-on connectivity.
