The UPS is a device that protects electrical equipment, in addition to allowing them to have a load so that they can be safely disconnected.

What are the advantages and disadvantages of nobreaks?
One of the main advantages of a UPS is the fact that they do not allow the flow of electrical energy to be abruptly interrupted by a power outage, as these energy peaks are often not even noticed by humans, but they affect many electronic equipment.
When a power outage occurs, his batteries are what keep the devices on until they can be turned off. Usually they are not able to keep you connected for a long time, but it is enough for you to save important documents and turn off the machine.

Which is better: Nobreak online or offline?
There are basically two types of UPS available for sale on the market today, offline and online. The first is considered more basic, while the second has more advanced technology and is slightly more expensive.
It stays off most of the time, and when a power failure occurs, its internal battery starts to be used.
Its operation does not occur as instantly as the online models, because the transfer time that the device needs to leave the inverter state and go to the network state is longer.
It is best suited for use in homes, businesses and small businesses, as it must be used with small equipment.
The inverter is always on, and its transfer time is very low when compared to offline models. They are mostly used for servers, hospitals and places where power outages can be very harmful.
Below is a table with the main differences between offline and online nobreaks:
The cost of a UPS can vary widely, but it is usually between R $ 200 and R $ 25,000, depending on some functions of the equipment and the fact that it is an online or offline model.

Purchasing criteria: Main factors for evaluating a UPS
There are certain characteristics that are fundamental to a UPS, such as those listed below:
Below we will detail the most important features so that you can choose the most suitable UPS for you.
Choosing the right size for your UPS is essential, because if you buy too big it will be an unnecessary expense of money, and if it is too small it may not be enough for what you want.
Making the right choice will ensure that you have enough power in the event of any power grid problems, which may mean that you will not delay the delivery of important projects, for example.
To know for sure how to dimension your UPS, follow the instructions below:
- See the number of devices you want to connect to the UPS (remember to add monitors, routers, etc. to this account).
- Find out the amount of amps and volts that each of them uses, and multiply these values in each of them, to get the VA (Volt-Ampere). If your equipment uses watts, you will have to divide this value by 0.65 to find the VA.
- Make the sum of all VAs of the equipment, to know the total VA that will be connected to your UPS.
- The bills do not end there, because you should calculate the VA of your UPS taking into account that you can buy other equipment in the future, so leaving a gap between 15% and 30% more is ideal. Therefore, multiply the value of the previous item by 1.15 or 1.30.
Thus, your sizing will be complete, and you will be able to buy your UPS more safely, knowing that it supports the amount of equipment you want to connect to it.
Not all nobreaks have a display, and you may not even care about it, but you can’t deny that this item can be very useful, as it allows you to know exactly what is happening with your equipment, with information such as battery, when the battery needs to be changed, among other things.
If it does not have a display, you are subject to having to receive the information it sends only via USB cable, or, in the worst possible way, when it sends beeps in the form of a beep.
To avoid being subject to these situations, buy equipment that has a display, so that you are always up to date with what is happening with the device.
The equipment that emit noise is usually the one that has a fan at the rear, which is normally what happens with larger devices.
Smaller equipment and homes are not subject to this type of problem, as nobreaks are usually quite quiet when they do not have a fan.
To know for sure that the UPS you want to buy tends to make a lot of noise, see the reviews of other users who use the equipment before making the decision to purchase the device.
Are you sure how the UPS batteries you want to purchase work?
This is essential information so that you will not be disappointed after the purchase, as there are some factors to consider, such as the following:
- Can the battery be changed by the user or must it be changed by someone special?
- How much does the battery cost?
Buying equipment that does not allow the user to change batteries ends up being exhausting, as you will have to spend money on a technician, in addition to the price of new batteries.
So always choose a model that allows you to make this exchange without too many problems. In addition, of course, a UPS that has batteries that do not cost too much.
In this home video below you can get an idea of how it is possible to change the battery of a UPS:
One of the most important things to think about before purchasing a UPS is about its autonomy, that is, how long the system can support your infrastructure.
The rule is that the more battery and less equipment are connected to it, the greater its autonomy.
The fact is that a UPS, especially domestic models, was not made to keep a system on for a long time, but to provide a way to turn it off as safely as possible.
Environments such as hospitals and companies, which cannot have their devices turned off, have to use much more sophisticated devices, and even generators to avoid irreparable losses.
