Welcome to the ultimate best UPS guide. And it is that possibly you have ever felt a little frustrated to see how your computer turned off suddenly and without warning, either when the power supply was cut for a few minutes or just a second.
In those cases, there was no other option but to restart the computer and start from scratch, opening all the applications that were being used. However, this is something that could easily have been avoided by using a UPS, a battery that will give your computer enough power at a time when the power goes out.
As for laptops, it is normal that they work differently with respect to energy. If they are unplugged from the electrical outlet and have been unused for several minutes, they will automatically enter sleep mode or turn off. This has to do with the power management options included in the operating system for mobile devices.
However, this function similar to that used by a laptop can also be replicated on a desktop computer using a UPS. With this, the equipment can be configured to enter hibernation mode or directly turn off when there is no electrical power and the only source is the UPS.
These are just two practical cases in which it can be very useful to use a UPS and take advantage of the benefits it offers.

What is a UPS and what is it for?
A UPS serves both to safeguard the data of a device connected to it and to maintain the voltage on occasions when it is destabilized.
These equipments are manufactured with different sizes, designs and specifications, so it is convenient to know in advance what use will be given and what devices will be connected to it.
Having a UPS in a home or office is essential when a lightning bolt strikes a transformer during an electrical storm, which can cause it to travel at high speed through internal wiring and reach the PC. If this happens, the first thing that ends up being damaged is the power supply.
An uninterruptible power supply (UPS) is a backup battery that has as one of its functions to be able to provide an extra power source for electrical devices such as computers, printers and televisions.
Also, with the use of a UPS, you can also connect the computer monitor, so if the power goes out, you can continue working for several more minutes with the computer, depending on the capacity of the UPS.
Another extremely important function of a UPS is to stabilize the energy flowing to electrical devices, thus ensuring that there are no current peaks, drops and overvoltages, frequency instability or noise interference. This prevents faults from occurring if the devices are not receiving a constant flow of electricity.
Although a UPS is not essential to use with other electronic devices, its use is recommended to avoid the problems mentioned above, so that the power supply will have more reliability, ideal for areas such as medicine, where equipment is used important for health that must work 24 hours.
These are the different names that can be used to describe a UPS:

As for the most popular UPS manufacturers, we can cite APC, Belkin, CyberPower, Ultra, Salicru and Tripp Lite, among many others.
A UPS is activated immediately after a power outage, something that will give you time to continue using the device for a few more minutes and to be able to turn it off correctly. In the case of a computer, you can save the work you are doing, close all the programs and turn it off from the same operating system.
During this time that the UPS is supplying power to the equipment, this time can be used to properly shut down the equipment or to search for and connect another additional power source.
This backup battery not only works for computers, but also for many other devices, with which the energy consumed by each one will have to be taken into account to determine which UPS is suitable.
Similarly, the UPS will vary in size according to the devices it has to cover. The model for a gaming computer will be different from the model aimed at supporting a data center or server.
How a UPS works internally
As a first step, the UPS consumes AC power and stores a part of it in the backup battery, and then, in a second step, clean it and transfer it to the device connected to the UPS.
This UPS process requires three essential components: a charger, a battery, and an inverter.
The charger is in charge of transforming the alternating current taken by the UPS into direct current, which will be stored in the battery, while the inverter transforms this direct current into alternating current, which is used by the devices connected to the UPS when produces a power outage.
Therefore, the operation and effectiveness of the UPS will be determined by how these basic components are configured, and what other extra functions and design it has.
Various conflicts with energy
As we have mentioned before, a technological device can be damaged by different unexpected and problematic events with the electrical energy of a home or office. However, not all power problems are created equal, and not all UPSs cover all of these complications. We will see what events can occur when using a device connected to a power outlet.
Power suspension
This event can happen in cases where a power line or transformer was damaged. Over the years, PC programs have been refined and have begun to react differently to power outages. For example, starting with Windows 95, when a PC accidentally shuts down, the system makes a diagnosis by looking for faults on the next restart of the PC.
With the advent of Windows NT, the operating system began to recover from these power interruptions more smoothly.
Decrease in tension level
This happens at the moment when an overload of electrical circuits occurs. If you have multiple electrical devices in use simultaneously, this overload may be able to cause a cut in the electrical power supply.
This inconvenience in the electrical energy could be guilty of failures and damages in the devices that were being used at the time, despite the fact that these overloads last a few seconds and appear unexpectedly.
Interferences in energy
Usually caused when generators or lightning strikes interfere; it follows that the quality of the energy is poor and dirty, reaching the devices with the probability of risk of damage to them.
Faced with this problem, it may happen that some applications or the operating system start to malfunction, with the possibility of damage to some files.
Peak voltage
It occurs when there is an unforeseen increase in electrical voltage, which generally lasts for a few seconds. The factors for this to occur are related to lightning or the return of energy after a power failure.
At the time this occurs, what is usually recommended to do is disconnect electrical devices to avoid damage. When the electricity returns, you have to wait a moment until the voltage is regularized, then afterwards, reconnect all the electrical equipment.
In some cities, electricity distribution companies may warn users that power will be interrupted.
Power overload
This is a sustained increase in electrical voltage that is caused by electrical equipment, such as an air conditioner or refrigerator. The overvoltages have a fairly short duration, although they are capable of causing major damage to any electrical device, especially to PC hardware.
How to choose the right UPS
The protection you will assign to your PC will not be the same for all users, as there may be different needs. There are various options for sale in the market that are oriented to different areas, such as an office, a home or even a data center.
To facilitate the choice of the perfect UPS according to the user's needs, we will mention several points to keep in mind when buying an uninterruptible power supply:
- Complete cancellation of electrical voltage peaks that can cause damage to electrical equipment.Indicator of errors in the wiring of the room, which prevents the equipment from being damaged due to not being properly grounded. thus preventing the data of the electronic device from being corrupted. Power supply instantly when an unexpected power interruption arises. Possibility of connecting multiple devices. Special functions and features, such as notifications when it is necessary to replace or manage the UPS battery. Also, the UPS should give the possibility to save the tasks that were being done in the equipment at the moment of the power cut and automatically shut down.
These features may only be found in the most advanced and highest priced UPS models.
Buying a UPS is a significant investment, so in addition to the features, you must ensure that it includes a good lifetime warranty that covers any repair you need.
Technology devices in a home have advanced steadily for many years, so it is not surprising that some people have servers and NAS devices in their homes, sophisticated equipment that performs important tasks for many hours, making a UPS it is essential in these settings.
In such cases, further analysis is required on which UPS model is the most suitable for each configuration, bearing in mind that for a traditional PC a different UPS will be required than for an advanced server, for example.
What are the different types of UPS
With three different types of UPS among the most outstanding, these uninterruptible power supplies are flexible to be incorporated in different environments and applications, being able to cover the needs in a home or in a company.
An Offline or Standby UPS is capable of alerting about electrical faults and acting automatically, leaving aside the power from the outlet to start using its own backup power.
The other two types of UPS are Line Interactive and Online, the latter being the most expensive in terms of price. With any of these UPSs, the electronic devices will remain in operation even when there is an interruption in the supply of electrical energy.
However, each of these types of UPS have their special functions and characteristics, as well as the method they use to measure energy, which is why we will analyze each one to know their differences and which is the best in different situations.
What is a Standby UPS?
A Standby UPS, which is also often called Offline UPS, is a word that clearly describes it and makes a difference with another type of UPS, the Online, which provides power without interruption. The most common Standby UPS provides power for a few minutes thanks to its battery, which acts in moments of interruptions.
With this UPS, the connected equipment will receive power in the normal way, while the UPS will remain in standby until the moment a problem in the power supply occurs and the backup battery is required.
According to the model, an Offline UPS is also trained to offer data protection and act quickly to prevent equipment from falling, spikes and surges. In these types of UPS you can find models of compact size, ideal for use in a home.
A Standby UPS is usually used to provide protection to computers, VoIP equipment, routers, and various devices that require constant power without losing data. It is also the cheapest UPS of the three types.
Consequently, a Standby UPS will offer a few minutes of standby power in a home environment and in work environments that do not have too rigid needs.
These and Line interactive will be the most common in our home or small office
What is a Line Interactive UPS?
A Line Interactive UPS is capable of managing the electrical voltage automatically, being able to act in both high and low voltage situations.
When using a Line Interactive UPS, the main source of energy is electricity from the outlet. Anyway, inverter / converter technology makes the UPS battery charge during normal use.
When a power outage occurs, the UPS enters the scene to convert the power from its previously charged battery into AC power, to supply it to the device that has run out of power. In this way, the UPS can provide power for 5 to 30 minutes, depending on its model.
Line Interactive units are priced higher than Offline UPSs, although they are also cheaper than Online models. A Line Interactive UPS will be in charge of maintaining the correct operation in unforeseen cases of power failures and low voltage in a short period of time. If it is already known that the power outage will last a long time, this UPS will give the possibility to shut down the devices safely to avoid damage.
What is an Online UPS?
It is a type of UPS similar to Line Interactive, although it is made up of a rectifier that directly manages a DC / AC inverter, even at times when it receives power from normal alternating current.
An Online UPS benefits from a double conversion system, which means that the network equipment is not powered by electricity from a direct outlet, but instead goes through a process in which alternating energy reaches the rectifier to become continuous energy. From there it is transferred to the battery, to then reach the inverter again.
Once the alternating energy is stored in the inverter, it is finally diverted to the device connected to the UPS that needs power.
Thanks to this complex process, the devices connected to the Online UPS are systematically powered by clean energy.
In the event of an unexpected power outage, the Online UPS will be ready to continue to supply a continuous stream of power in order to protect the device connected to the UPS.
If an error occurs in the energy flow, the rectifier would be in charge of deviating automatically, causing the battery to provide the necessary energy until the problem with electricity is solved.
The operation of the Online UPS is uninterrupted, which means that it will be constantly transferring power to the connected device. This is one of the reasons that explain the high prices of these equipment, being more expensive than Offline and Line Interactive.
There are various models of Online UPS that meet different configuration needs.
Thanks to the double conversion, it is possible to provide solid protection to different equipment such as data centers, network servers and a wide range of environments. Also, and something that represents a great advantage, is that there is no delay when the battery should go into action, which means that there is no possibility of data loss.
Generally, the larger the size of the UPS, the more capacity it will have to maintain itself for a long time by supplying power to the device that needs it.
Finally, this type of UPS includes a status monitoring function, with which it checks the battery charge level and its availability, and can alert to problems or power failures (surges, for example) to the PC.
Advantages of using a UPS
It is not an exaggeration to think that there is always a chance that a computer's power supply will fail or be a victim of power surges. All this does nothing but damage and problems for the devices of a business or a home.
In servers and data centers, electricity is an extremely important element, so they are manufactured so that they receive constant traffic of this energy. However, this energy traffic provided by electricity companies can sometimes fail, experiencing certain instabilities.
In times of temporary power outages, power surges, or interference, various inconveniences may arise, possibly resulting in damage to the electronic device.
While power generators are capable of providing the power a data center or server needs when a power outage occurs for several hours or days, they are not helpful when there are momentary power fluctuations.
To give us an idea, it is possible that at some point the electricity supplier will launch a significant inductive load, so you could warn the consequences as a brief event on the line, although in fact of great damage power.
In cases of this type, you would not receive an alert to avoid exposing yourself to this risk, so you would not have time to change the power supply to an electric generator. However, these events can be counteracted with the use of a UPS.
A UPS will not only act when an electrical blackout occurs, but they will also protect electrical devices such as those mentioned above, thereby keeping the energy flow clean and also preventing damage to them.

Conclusion about the best UPS
The UPS makes up a substantial part of the entire energy system of a server, data center or home PC. Although UPSs do not have enough capacity to prolong the operation of an equipment with its own energy when a blackout occurs, they are capable of providing the necessary protection for a short period of time, thus preventing damage to the equipment and also the possibility of making a correct and secure logout. And as an extra advantage, if you have an electric generator, the UPS will give you time to activate it and thus continue with your activity until the power returns.
Certain UPSs are considered useless as they provide few minutes of power. Although one thing to keep in mind is that with up to five minutes of additional power, it is enough to close all open programs, save the documents in use and make a safe shutdown of the equipment, thus avoiding damage to the hardware.
