  • 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.
  • Standby Topology
    Ensures that when incoming power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts to AC power to run connected equipment.
  • 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™ High-Efficiency Design
    Reduces power consumption by utilizing a compact charger and power inverter to create an ultra-efficient backup power system for home and office use.
  • Ultra Quiet Design
    Minimizes noise during operation for a quieter work environment.
  • Transformer-Spaced Outlets
    Accommodate large transformer-based plugs without compromising the access of other outlets.
  • PowerPanel® Personal Software
    Provides a user-friendly dashboard interface for controlling and monitoring the UPS. Free software download available.
    This model is an ENERGY STAR®certified Uninterruptible Power Supply (UPS) system. ENERGY STAR is the trusted, government-backed symbol for energy-efficient products and practices that help save money and protect the environment.
  • Three-Year Warranty
    CyberPower will repair or replace a defective UPS system (including batteries) within three years of the purchase date. See warranty for details.
  • Connected Equipment Guarantee
