How do I work out the right UPS for my needs?
The Cyber Power website has a great UPS selector tool or please contact us anytime for more information.

Can I connect 2 PCs to the UPS via a USB hub and carry out graceful shutdown of both PCs?
Unfortunately, all consumer UPSs are not capable of doing this. They can only connect a single PC via USB (or serial) cable and manage 1 PC. Only UPSs for enterprises and datacenters can manage multiple servers via the network.

If the run time of a 10W load is 30 minutes, will it be 60 minutes if the load is 5W?
Actually the discharge diagram of the battery is not perfectly linear but acts in a curve. So the estimation is not necessarily correct. Please refer to the run time information we provide.

Do greater loads have shorter UPS battery runtimes? What other factors can affect the run time of a UPS?
Yes. Generally greater loads yield shorter runtimes. However, there are still some other critical factors that can affect runtimes:

(1) Load type (power draining type):
Inductive loads like motors require high starting current and can drain more power than resistive loads (such as lamp). Furthermore, most of the time we only consider the rating power consumption of the load. One server can consume more power than another identical server if it is frequently under heavy-duty service.

(2) Battery condition:
Every single battery is in different condition. Of course batteries with better conditions can last longer.

(3) Operating environment:
The performance of the battery can vary dramatically under extreme temperature and humidity.

What is the warranted operating environmental limits?
Our operating environmental limits:
Temperature: +32°F ~ +104°F ( 0°C ~ 40°C)
Humidity: 0 to 90% non-condensing

Should I keep my CyberPower UPS on all the time? Or I should turn it off at night?
If the devices you want to protect (PC, servers, NAS and etc) are always on all the time, then definitely you should keep your UPS on. Otherwise you can choose either to keep the UPS on or turn it off since all of our UPSs are equipped with power-saving technology and they consume alot less idle power.

I am not getting any power from the battery outlets, what should I do?
Attempt to reset the UPS by doing the following steps:
(1) Turn the UPS off.
(2) Unplug everything from the UPS.
(3) Leave only the CyberPower UPS plugged into the wall socket.
(4) Wait for 15 seconds, then turn on the UPS.
(5) Three short beeps indicate that the unit is doing the self-test.
(6) Test the “Battery and Surge” outlets with a low wattage item such as a 60 Watt lamp.

Do I need to install PowerPanel software for my UPS to work properly?
Installing PowerPanel software will give you more additional features, control, and the ability to automatically shut down your computer in event of a power outage. That being said, the UPS will provide surge suppression and battery backup without using the software.

Why does my UPS beep twice when I turn it on?
This is normal operation of the UPS. All CyberPower UPSs perform a self test routine when they are turned on.

Will my CyberPower UPS work without the PowerPanel software?
Yes. The UPS can function well even without PowerPanel installed. However, your computer will not shut down automatically without the software. Besides it can also provide more features such as scheduling and actions for power events. To know more about our PowerPanel software, please refer to the PPPE/PPBE user’s manual available on our website.

My UPS emits a long solid beep. What should I do?
A long, solid tone indicates that your UPS may’ve had overloading situation.

First, please remove some connected electronics of lower priority from the “Surge Only” outlets and see if the warning beep stops.

If the overloading situation remains, you will need to remove some connected devices from the “Battery and Surge” outlets until the alarm is dismissed.

Can I use my UPS in conjunction with a generator?
Most of our UPS systems are not designed to work with generators (Except CyberPower Online Series and EPS Series).

Many generators produce “dirty” AC power that is improper to be used as the input power source of the UPS.

My UPS is emitting two short beeps every 30 seconds. What is happening?
This indicates that the UPS is running on battery power (input utility power is not available).

Several possibilities for this situation:
(1) The input power plug of your UPS is not well connected.
(2) The wall outlet you are using (UPS drains power from that wall outlet) is not providing power (can be outlet broken, or a blackout is taking place in your area).
(3) The power quality of input utility power is too bad.

Do I have to turn on the UPS in order to make it charge?
No, you don’t have to.
All UPS’s of CyberPower are equipped with “Auto Recharge” feature. The UPS will charge the internal battery as long as the input power source is available. (No matter the UPS is turned on or turned off)

I am using Mac computer. How can I make my Mac work with UPS?
You may like to try our Mac dedicated management software, PowerPanel® for Mac.
PowerPanel® for Mac allows you to view the status of your CyberPower UPS via the USB connection to your Mac. PowerPanel® works in conjunction with Energy Saver and adds more features include:

  • Monitor the status of the UPS and the AC utility power.
  • Keep track of the energy consumption in terms of kWh, carbon emissions and electricity cost.
  • Fully Integrate with Energy Saver and provide more function in addition to graceful shutdown of the computer.

What is the difference between the “Battery and Surge” outlets and the “Surge Only” outlets?
The “Battery and Surge” outlets are the outlets that can provide protection against surge during Line Mode operation and can provide backup power during Battery Mode operation.
The “Surge Only” outlets are outlets which can provide surge protection but will not receive battery power during power outages.

You should plug your PC, monitor and critical data storage devices into ” Battery and Surge ” outlets. Devices such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled “Surge Only” since these devices require high starting current and are less critical.

Can I increase the runtime by hooking up multiple UPS units in a row?
Absolutely Not. This configuration is called “daisy-chaining” and is a very dangerous approach. If you use UPS units in this way, you will void the UPS’s warranty.

The utility power failed and my equipment shut off immediately without having the battery power from the UPS. What was wrong?
Please make sure that your computer and devices are plugged into the “Battery and Surge” outlets. If they are using the “Surge Only” outlet, the connected equipment will not have power supply when the UPS switches to battery mode during blackouts.

Why is my CyberPower UPS beeping?
(1) If it emits several short beeps every minute:
It implies the UPS is working in Battery Mode.
The UPS will send out warning sound when the UPS is working on battery power. You can disable the sound if it is annoying. However, when UPS is running out of battery power, the warning sound will recover again and can’t be disabled.

(2) If it emits a long beeping sound continuously:
That means the UPS encounters overload or other serious faults.
You may have plugged too many devices on the UPS (probably also use power strip or extension plug to put on more devices) and have caused overload. You need to turn off the UPS first, remove some devices and turn on UPS again to make it work.
If the overload situation remains, you need to remove more devices.
If all loads are removed and the long beep remains, the UPS may be faulty and please contact our local service or dealer.

When utility power recovers, why my computer protected by UPS cannot auto restart itself?
If your computer is of ATX type, you should change the setting in BIOS to allow auto restart when utility power recovers.

Why are the outlets not passing utility power to the equipment in Line Mode?
Please check first whether the circuit breaker is disconnected due to overload. If yes: (1) Turn the UPS off and unplug at least one connected device.
(2) Unplug the power cord of the UPS and wait for 5 minutes.
(3) Press the circuit breaker to recover.
(4) Connect power cord and turn the UPS on.
(5) If the procedure above can’t help your UPS work normally, please contact our local dealer for assistances.

If the UPS is not overloading and still not providing power in Line Mode, please contact our local dealer for assistances.

Which devices are NOT allowed to be plugged into the UPS?
Any device which exceeds the CyberPower UPS’s VA/Watt rating should not be plugged into the outlets. Besides, high current-drawing devices, medical equipment is also not recommended for ordinary UPS models.

Below are the typical devices that we believe you should not plug into the “Battery and Surge” outlets of the UPS. Please note that there are others not listed.

(1) Laser printers
(2) Space heaters
(3) Copiers
(4) Paper shredders
(5) Vacuums
(6) Curling Irons

Can I hookup a power strip (or extension cord) to the UPS?
Regarding safety issues, power strips (or extension cord) cannot be installed before (input) or after the UPS (output).

If you need additional outlets, we recommend that you upgrade the UPS to a unit that has more outlets. Or you have to calculate and make sure that you won’t put too much load via the power strip.
If you need a longer input cord, you can purchase a UL certified extension cord that is rated for the respective current of the unit. This cord MUST be a single-outlet extension cord.

Why does the displayed load level on the UPS appear different from the actual load? Is there something wrong with my UPS?
Due to the sensitivity of the sensor, when the connected load is too small, the indicated readings of load level will tend to be inaccurate. Generally the indicated load level will be more accurate when it exceeds 10%~15% of the total capacity. As a result, when you connect a very small load on your UPS and it fails to display very precisely, it doesn’t mean your UPS is faulty.

Why is the fan of my CyberPower UPS keep turning? Can it be stopped?
There are several situations that will trigger the fan operation:
(1) Load level increases to a certain level (varies by model) in line mode (AC mode) operation.
(2) AVR is activated and working (in line mode).
(3) UPS is working on battery power (battery mode).

The operation of fan is necessary and crucial for UPS to provide normal operation and consistent protection. It can’t be disabled or stopped by user.

What types of UPS systems are available?
UPS Systems are available in three different topologies:

• Standby (also known as “Off-line”)
• Line-Interactive (also known as “AVR”)
• Online (also known as “Double Conversion”)

Standby Topology
Standby is the most basic UPS technology. When there is a brown/blackout, the UPS simply resorts to the internal battery to provide electricity to the equipment. These UPS systems are designed for consumer electronics, PCs, POS/security systems, and other basic equipment.

Line-Interactive Topology
Line-Interactive systems incorporate technology that allows the UPS to correct minor power fluctuations (brownouts, over voltages, etc.) without switching to battery. This extends the life of the battery and is an essential feature in areas where power fluctuations occur on a regular basis. Typical applications are consumer electronics, PCs, and mid-range servers.

Online Topology
Online systems provide consistent, clean, and perfectly stable power regardless of the condition of the incoming power. These systems operate on isolated battery supplied power all the time and have a zero transfer time because they never have to “switch” to battery. Online UPS systems are designed for high-end system components, corporate servers, lab equipment, and other sensitive electronic equipment.

What are the major types of output waveforms in UPS systems?
The utility power company supplies AC power of pure sine wave waveform. However, most consumer electronics in daily life do not require the pure sine wave power to function properly. As a result, the UPS systems of simulated sine wave waveform become the most common and economical solution.

Simulated sine wave UPSs are equipped with less expensive technology to produce output power from internal battery, and are very commonly seen in entry/mid-level UPS systems. UPS manufacturers provide different types of simulated sine wave (Modified, Quasi, Stepped, PWM, and etc.) but the basic characteristics of the output power are similar.

For those applications that require high quality power, UPS systems with the pure sine wave output are also available. These UPS systems are designed for electronic devices equipped with APFC power supplies or small AC motors which require pure sine wave power to function properly.

As a side note, the output waveform of UPS is only an issue when the UPS is working in “Battery Mode” which is providing power to the equipment by its internal battery. If the UPS is working in “Line Mode” (or known as “AC Mode”), the UPS is supplying the pure sine wave directly from utility power to the connected equipment.
