Product Description

Product Overview


The CyberPower ST900U uninterruptible power supply (UPS) system provides battery backup and surge protection for lightning-induced surges and other power events that can damage electronic equipment. This unit delivers enough battery backup to power connected electronics through utility power failure and enough runtime to perform a graceful shutdown to protect against the loss of data and damage to valuable electronics during longer outages.

The ST900U has two USB charging ports with 2.1 amp shared total output which gives you a faster charging time. This unit is designed to minimize noise for a quieter work environment and to run efficiently to reduce power consumption. Including a sleek design, this UPS is perfect for all your home office and entertainment needs, including computers, gaming consoles, and broadband routers.

With a $125,000 lifetime connected equipment guarantee and a three-year warranty, you can trust CyberPower’s commitment to the quality of this Battery Backup with Surge Protection.

  • 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.
  • 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.
  • USB Charge Ports
    Rapidly charge and power USB devices such as tablets (including iPad), smartphones, MP3 players, and other mobile accessories.
  • PowerPanel® Personal Software
    Includes a free software download that provides a user-friendly dashboard interface for controlling and monitoring the UPS.
  • 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.
  • Transformer-Spaced Outlets
    Accommodates large transformer-based plugs without compromising the access of other outlets.
  • ENERGY STAR®
    This model is an ENERGY STAR® qualified 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 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.

GreenPower UPS Technology: High-Efficiency Design

GreenPower UPS™ Technology from CyberPower improves operating efficiency, reduce heat generation, and consume less power than conventional UPS models.

High-Efficiency Design significantly decreases power consumption to create an ultra-efficient backup battery for home and office use.


Transformers and Transformer Outlets

A transformer converts alternating current line voltage to a higher value or a lower value. Transformers rely upon electromagnetic induction, the process which occurs when the alternating current within a circuit generates current in a nearby circuit.

Transformers vary in design and size, as well as using different amounts of current. Small transformers plug into a wall outlet and create low direct current voltages which are used by common electronic devices. Transformer outlets are more widely spaced than other outlets to accommodate transformer block adapters or other adapters that are large in size. Transformer outlets can be used to connect any appropriate device to a surge protector.
