A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD CST135UC provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CST135UC 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 USB charge ports (one Type-A and one Type-C) power portable devices such as mobile phones and tablets, even during a utility power failure. The CST135UC comes with a one-year warranty (including coverage of batteries) and a $500,000 Connected Equipment Guarantee.
Features

- 10 NEMA 5-15R Outlets
- Multifunction LCD Panel
- USB Charge Ports
- Data Line Protection
- Widely Spaced Outlets
- Automatic Voltage Regulation (AVR)
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.
Automatic Voltage Regulation (AVR)
AVR increases the AC power and maintains a safe voltage level without switching to battery mode and conserves battery life.
Multifunction LCD Panel
Displays immediate, detailed information on the battery backup and power conditions, alerting users to potential problems before they can affect critical equipment and cause downtime.
USB Charge Ports
Rapidly charge and power USB devices.
Data Line Protection
Prevents power surges that travel through coaxial and Ethernet lines from causing damage to electronics.
Widely Spaced Outlets
The widely-spaced outlets allow you to conveniently add transformer-sized plugs without blocking other outlets.
Ultra Quiet Design
Minimizes noise during operation for a quieter work environment.
Audible Alarms
Provides audible notification of certain events such as running on battery power, low battery, or overload conditions.
PowerPanel® Personal Software
Provides a user-friendly dashboard interface for controlling and monitoring the UPS. Free software download available. See the Resources tab.
Simulated Sine Wave Output
Provides a manufactured waveform output to supply cost-effective battery backup power for equipment that does not require sine wave output.
Line Interactive Topology
Exists when a line interactive UPS has an autotransformer that regulates low voltages (e.g., brownouts) without having to switch to battery.
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.
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.
