The batteries have been replaced by the manufacturer as part of the re-conditioning process.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 CST150UC provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking equipment, smart home devices, and home entertainment systems.

The CST150UC 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.

Product Features

• Battery BackupSupplies 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 ProtectionDiverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
• Automatic Voltage Regulation (AVR)Increases the AC power and maintains a safe voltage level without switching to battery mode and conserves battery life.
• USB Charge PortsRapidly charge and power USB devices whether the UPS is providing utility or battery backup power.
• Multifunction LCDDisplays immediate, detailed information on the battery backup and power conditions, alerting users to potential problems before they can affect critical equipment and cause downtime.
• Data Line ProtectionPrevents power surges that travel through coaxial and Ethernet lines from causing damage to electronics.
• Line Interactive TopologyExists 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.
• Simulated Sine Wave OutputProvides a manufactured waveform output to supply cost-effective battery backup power for equipment that does not require sine wave output.
• ENERGY STARThis 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 DesignA 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 DesignMinimizes noise during operation for a quieter environment.
• PowerPanel® Personal SoftwareProvides a user-friendly dashboard interface for controlling and monitoring the UPS. Free software download available.
• Connected Equipment GuaranteeCyberPower will repair or replace properly connected equipment if it is damaged by a power surge.
