The batteries have been replaced by the manufacturer as part of the re-conditioning process.

A mini-tower UPS with line interactive topology, the CyberPower CST1500S provides battery backup (using sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems requiring active PFC power source compatibility. The CST1500S 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.

Two Type-A USB charge ports power portable devices such as mobile phones and tablets, even during a utility power failure.

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.

Sine Wave Output
The UPS generates energy that is identical to, or cleaner than the utility company’s power grid. Benefits include low total harmonic distortion, minimal electrical noise, and optimal line clarity.

Multifunction LCD Panel
Displays immediate, detailed information on the UPS battery and power conditions, alerting users to potential problems before they can affect critical equipment and cause downtime.

Automatic Voltage Regulation (AVR)
AVR increases the AC power and maintains a safe voltage level without switching to battery mode and conserving battery life.

USB Charge Ports
Rapidly charge and power USB devices whether the UPS is providing utility or battery backup power.

Data Line Protection
Prevents power surges that travel through coaxial and Ethernet lines from causing damage to electronics.

Widely Spaced Outlet(s)
The widely-spaced outlet allow you to conveniently add transformer-sized plugs without blocking other outlets.

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.

ENERGY STAR
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.

GreenPower UPS™ Bypass Design
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 Software
Provides a user-friendly dashboard interface for controlling and monitoring the UPS.

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