Overview

Product Overview

A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD CST135UC2 provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CST135UC2 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. An advanced multifunction control panel with a color LCD clearly communicates UPS status with green, yellow, or red icons, and the configurable battery + surge outlets allow prioritization of runtime for critical equipment. The CST135UC2 comes with a three-year warranty (including coverage of batteries) and a $500,000 Connected Equipment Guarantee.

GreenPower UPS Technology: Bypass Design

GreenPower UPS™ Technology from CyberPower improves operating efficiency, reduce heat generation, and consume less power than conventional UPS models.

Our patented Bypass Design allows current to bypass the transformer and automatic voltage regulation (AVR) when utility power is normal, thus reducing energy consumption and associated costs. Because utility power functions normally most of the time, the bypass design allows for substantial energy savings. This technology also reduces heat generation, an important factor in decreasing operating costs.

Automatic Voltage Regulation

Automatic Voltage Regulation (AVR) in line interactive UPS systems stabilizes the incoming AC signal to maintain output power at a nominal 120 volts by controlling high and low voltages without resorting to battery power. This significantly increases battery life and lessens the likelihood of data loss, memory freezes, and system crashes.

How AVR Works in a Line Interactive UPS

A line interactive UPS includes an AVR autotransformer a special type of transformer designed to switch between powered coils of wire in response to variances in utility power input, thereby increasing or decreasing the magnetic field and the resulting output voltage to connected equipment.

This type of UPS tolerates undervoltage brownouts and overvoltage surges without consuming backup battery power by automatically selecting different power taps on the AVR autotransformer. During normal operation, incoming AC power bypasses the autotransformer (where voltage highs and lows are controlled) while also charging the battery. When the incoming voltage falls below the AVR range, the UPS switches to battery backup, and the DC-AC inverter circuitry is engaged. Power will continue to be supplied by the battery-inverter circuit until incoming voltage returns to the range manageable by the AVR.

Transformers and Transformer Outlets

A transformer converts alternating current line voltage to a higher value or a lower value. Transformers rely upon electromagnetic induction, the process which occurs when the alternating current within a circuit generates current in a nearby circuit.

Transformers vary in design and size, as well as using different amounts of current. Small transformers plug into a wall outlet and create low direct current voltages which are used by common electronic devices. Transformer outlets are more widely spaced than other outlets to accommodate transformer block adapters or other adapters that are large in size. Transformer outlets can be used to connect any appropriate device to a surge protector.

What is the USB/Serial port for?

The USB/Serial ports allow you to connect your UPS system to a computer and access additional power management features using our PowerPanel Business software. Note: PowerPanel Business must be installed on the connected computer. View the Downloads tab for additional information.

Can I use my UPS in conjunction with a generator?

CyberPower Smart App Online Series UPS systems include a Generator Mode setting specifically designed to work with generators. With varying loads, the frequency output from generators can be erratic. This erratic output can make it difficult for a UPS without a Generator Mode setting to recognize the input power, causing the UPS to function on battery power only. With Generator Mode, the UPS can automatically adjust to frequency fluctuations and maintain a full charge of the batteries.

LCD Control Panel
Enable Generator Mode from the LCD control panel.

Do I have to have the UPS turned on in order for it to charge?

The UPS will charge the battery whether the unit is turned on or turned off.

What types of equipment are NOT allowed to be plugged into the UPS?

Any device which exceeds the unit’s VA/Watt rating should not be plugged into the outlets. High drain devices, medical equipment, and aquatic equipment also void the unit’s warranty. Below is a list of other devices that also void the warranty.

  • Laser printers
  • Space heaters
  • Copiers
  • Paper shredders
  • Vacuums
  • Curling irons

Do I need to install PowerPanel software for my UPS to work properly?

PowerPanel software is not required for the UPS to provide surge suppression and battery backup. However, installing the PowerPanel software provides additional features and control for the UPS, along with the ability to automatically shut down your computer in event of a power outage.

Where is the serial number located on the UPS?

Your CyberPower product serial number (S/N) is located on a small white rectangle label located on the bottom or back panel of your UPS system. The serial number will appear in various places depending on the product you are referencing.

SX650U Serial Number

The label will have a barcode with a 12-character code right below it–this is your serial number. It may include your product’s model number and the words Made in China.

Serial Close Up

What is the difference between the Battery/Surge outlets and the Surge outlets?

Many CyberPower UPS units have two sets of outlets. One set is labeled “Battery/Surge” and one set is labeled “Surge”. The outlets labeled “Battery/Surge” are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.

Items such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled “Surge.” These outlets are intended for low priority electronics that are not essential to the PC’s main operation.

Why does my UPS beep twice when I turn it on?

This is normal operation of the UPS. All CyberPower units perform a self-test routine when they are turned on.

Can I hook up a surge strip to the UPS unit?

Surge strips cannot be installed before OR after the UPS unit. Doing so will void the UPS’ warranty. If you require additional units, please upgrade your UPS to a unit that has more outlets.
