A compact UPS with line interactive topology, the CyberPower CP685AVRG provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CP685AVRG uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. Battery Backup Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown. Surge Protection Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage. Data Line Protection Prevents power surges that travel through telephone, coaxial, and Ethernet lines from causing damage to electronics. Line Interactive Topology Exists when a line interactive UPS has an autotransformer that regulates low voltages (e.g., brownouts) and over voltages (e.g., spikes) without having to switch to battery. Automatic Voltage Regulation (AVR) Provides clean, consistent AC power by automatically increasing (boosting) low voltage without using battery power when incoming utility power experiences minor fluctuations. Simulated Sine Wave Output Uses pulse wave modulation to generate a stepped, approximated sine wave to supply cost-effective battery backup power for equipment that does not require sine wave output. GreenPower UPS™ Bypass Is a patented design that allows utility power to bypass the UPS transformer, when AC power is stable, which reduces energy consumption, noise, and heat buildup. Ultra Quiet Design Minimizes noise during operation for a quieter work environment. Transformer-Spaced Outlets Widely spaced outlets accommodate transformer-based plugs without compromising the access of other outlets. PowerPanel® Personal Edition Software Provides a user-friendly dashboard interface for controlling and monitoring the UPS. Free software download available. See the Resources tab.
