The CyberPower CST135UC2 is a mini-tower UPS (Uninterruptible Power Supply) with line interactive topology that provides battery backup and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. With a capacity of 1350 VA / 810 W and simulated sine wave output, it delivers reliable power protection with 10 outlets total: 5 surge-only outlets and 5 outlets with both surge protection and battery backup.

The unit features Automatic Voltage Regulation (AVR) that corrects minor power fluctuations without switching to battery power, extending battery life and protecting against brownouts. It offers 1500 Joules of surge protection and includes data line protection for network and coaxial connections. The CST135UC2 provides approximately 10 minutes of runtime at half load or 2 minutes at full load during power outages.

An advanced multifunction control panel with a color LCD display clearly communicates UPS status with green, yellow, or red icons, making it easy to monitor battery and power conditions at a glance. Two USB charge ports (one Type-A and one Type-C with 30W total output) allow you to power portable devices like mobile phones and tablets, even during a utility power failure. Configurable battery + surge outlets allow prioritization of runtime for critical equipment.

The widely-spaced outlets accommodate transformer-sized plugs without blocking other outlets. The unit features ultra-quiet operation to minimize noise, GreenPower UPS bypass design to reduce energy consumption when AC power is stable, and is ENERGY STAR certified for energy efficiency. Includes PowerPanel Personal management software for monitoring and control, plus audible alarms for events like low battery or overload conditions.

The CST135UC2 comes with a three-year warranty including battery coverage and a $500,000 Connected Equipment Guarantee. Includes UPS unit, user manual, function setup guide, and USB A+B type cable.
