CyberPower CP685AVRG 685 VA Line-Interactive UPS | Compact Desktop

Protect critical low-power equipment from the kind of electrical problems that interrupt work without warning. The CyberPower CP685AVRG uses line-interactive topology and automatic voltage regulation to handle common voltage fluctuations before they become battery events, helping preserve runtime for true outages. With 685 VA of capacity, it is a practical fit for routers, modems, VoIP phones, desktop peripherals, and other compact systems that need dependable backup without the footprint of a larger UPS. This model is built for straightforward deployment in tight spaces. Its compact form factor makes it easy to place beside a workstation or network shelf, while the 120 V output and AVR support help keep connected devices within a stable operating range. For environments where a sudden reboot can mean lost work or dropped calls, the CP685AVRG provides a measured layer of protection that is more capable than a basic surge strip and more efficient than oversizing the power path. Choose it when you need practical battery backup, voltage correction, and a small physical footprint for essential electronics that must stay online long enough to ride through short power events or complete a controlled shutdown.
