CyberPower CST1400S-R 1400VA/900W PC Battery Backup UPS Series - New Battery, Manufacturer Refurbished and 1-Year Warranty



A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD CST1400S provides battery backup (using sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CST1400S uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently. The CST1400S comes with a three-year warranty and a $500,000 Connected Equipment Guarantee.


  • 1400VA/900W Simulated Sine Wave UPS
  • 10 Total Outlets
  • Frequency 60Hz ± 3Hz
  • Quiet Operation
  • Voltage 90VAC – 140VAC

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.

Sine Wave Output

Provides power protection to ENERGY STAR® 5.0 systems with Active PFC power supplies.

USB Charge Ports

Charge and power USB devices such as tablets (including iPad), smartphones, MP3 players, and other mobile accessories.

Multifunction LCD Panel

Displays real-time information about the status of the battery backup and power conditions.

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.

PowerPanel® Personal Edition Software

Provides a user-friendly dashboard interface for controlling and monitoring the UPS. Connect your computer to the HID-compliant USB port or serial port (if available) to use the power management features provided by PowerPanel® Personal Edition software. Free software download available. See the Resources tab.

Connected Equipment Guarantee

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