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 regulating low voltages and over voltages, within defined tolerances, when incoming utility power has 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. Multifunction LCD Panel Displays immediate, detailed information on the battery backup and power conditions, alerting users to potential problems before they can affect critical equipment and cause downtime. USB Charger Two 5Vdc USB charging ports with 2.1A support located on the front panel for convenient access to charge portable electronic devices such as tablets, mobile phones, MP3 players, and cameras.
