PC users often have problems with the power of the computer, which often lead to the failure of individual elements, and they sometimes cost a lot of money. In order to reduce the risk of equipment malfunctions, users purchase uninterruptible power supplies (UPS). If in your house power outages occur quite often, then it is better to invest in UPS than to pay for repairs later, or even buy, for example, a new motherboard.
The battery built into the uninterruptible power supply for the computer will allow you to correctly shut down the device in the event of a power outage. You must admit that it’s not entirely pleasant when the power goes out at the most inopportune moment.
Before choosing a power supply for your computer, you need to know the following:
1. What kind of malfunctions occur in your home and how often they can be observed. Agree, it makes no sense to buy an expensive UPS with a high degree of protection, if there are practically no power failures in your house, and you decided to buy an uninterruptible power supply for your computer for safety reasons.
2. The power of all the equipment that you are going to protect. Upon learning this, you need to choose a UPS in which this parameter will exceed the capacity of the entire system by 20-30 percent. You can also buy an uninterrupted power supply for a computer with a reserve, in case you suddenly decide to change the equipment to more powerful.
3. The battery life that you need to complete all the computer processes. A typical UPS runs for 5-7 minutes offline.
4. How many pieces of equipment are you going to connect to an uninterruptible power supply. In accordance with this, you should choose an uninterrupted power supply for the computer, so that it is enough for all the devices that you are going to connect to it. If you use a modem, make sure that the telephone line is also protected.
It is important to know that all UPSs are conventionally divided into three types:
1. Uninterruptible power supply unit type offline.
This is the simplest and cheapest form. During a power outage, the backup power supply in the form of a voltage converter powered by a battery takes over the load. However, for this type of UPS, the voltage is not adjusted if the last indicator is exceeded in 180-250 volts, since there is no stabilizer here.
2. Line-interactive uninterruptible power supply for the computer.
This type has an automatic voltage regulator, which allows it to work with a voltage in the range from 160 to 290 volts. As a rule, such blocks have accompanying software, which allows you to automatically disable the computer software if the battery level tends to zero.
3. UPS type online.
This view constantly converts the mains voltage to direct and then to alternating current, generates energy in real time, which means that no switching occurs. These are the most reliable uninterruptible power supplies that are used for servers. As a rule, this type of device is not practical for ordinary PC users.
