Mini-tower UPS for desktop and networking gear

The CyberPower CST135UC is a line-interactive battery backup rated at 1350VA and 810W. It delivers simulated sinewave output to keep desktop computers, workstations, networking devices and home entertainment systems running during a power failure. Automatic Voltage Regulation corrects minor fluctuations without using the battery, extending its service life.

Thermals noise and power in normal use

The unit runs on utility power while AVR maintains a safe voltage level, switching to battery only when necessary. At full load the battery provides two minutes of runtime, while half load yields ten minutes for a controlled shutdown. Surge suppression is rated at 1500 Joules and includes EMI/RFI filtration to reduce line noise.

Ten NEMA outlets and dual USB charge ports

Five outlets supply battery backup and surge protection, while the remaining five provide surge-only protection for less critical equipment. One USB Type-A and one USB Type-C port charge phones or tablets even during an outage. Network and coaxial ports protect data lines, and a three-year warranty covers the batteries as well.

Questions about this item

How do I connect the CyberPower CST135UC to a wall outlet and which outlets provide battery backup?

Plug the unit into a grounded NEMA 5-15R wall outlet. Five of the ten rear outlets deliver battery backup and surge protection; the other five provide surge protection only.

When will the internal battery need replacement and what is covered?

The sealed lead-acid battery typically lasts three to five years. The three-year warranty includes battery coverage, so a replacement within that period is provided at no charge.

How long can the CST135UC run my equipment at full load before the battery is depleted?

At the full 810 W load the unit provides approximately 2 minutes of runtime, allowing time to save work and initiate a graceful shutdown.
