Product Overview

The CyberPower CPS300SL is the ideal model for entry-level computer systems. The CPS300SL guards against surges, spikes, sags, brownouts, and other power abnormalities. It also protects your computer system and valuable data during a power outage. The CP300SL comes with a three-year warranty and a $25,000 Connected Equipment Guarantee.

  • 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.
  • 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
    CyberPower will repair or replace properly connected equipment if it is damaged by a power surge.

Can I use my UPS in conjunction with a generator?

CyberPower Smart App Online Series UPS systems include a Generator Mode setting specifically designed to work with generators. With varying loads, the frequency output from generators can be erratic. This erratic output can make it difficult for a UPS without a Generator Mode setting to recognize the input power, causing the UPS to function on battery power only. With Generator Mode, the UPS can automatically adjust to frequency fluctuations and maintain a full charge of the batteries.
