Loss of unsaved data, software malfunction, and personal computer failure are the most common consequences of power surges in household power grids. Uninterruptible power supplies for computers will help to avoid them.
Invisible helper
Uninterruptible power supplies for personal computers are designed to protect your computer from failure if the power supply is turned off while it is running. First of all, with such a shutdown, the hard drive suffers, since it is for its correct operation that a constant power supply is required. Winchester is not just a block of memory, it is a device that stores your family archive, documentation, and PC software.
The uninterruptible power supply unit protects not only during power outages, but also from power surges, which are often caused by the most common reasons: connecting a water heater, vacuum cleaner, washing machine, in a word, any device with increased power consumption to the network.
The uninterruptible power supply also protects against undervoltage. Please note that voltage drops in houses over 20 years old are possible, due to the fact that many of them were designed with an estimated power consumption of 1.5 kW per apartment, and now this load reaches 10 kW. The devices simply do not have enough power, and therefore the power supplies are on. An uninterruptible power supply will smooth out the voltage surge due to the stabilizer, and with prolonged voltage surges, it will simply switch the power to the battery, which is built into the unit.
The uninterruptible power supply will protect your computer and in the event of currents in the network that lead to a short circuit, this device will also help in case of a power outage, will allow you to monitor the network parameters. Many units are supplied with special software for displaying the parameters of the power supply.
The price of power supplies starts from 2500 rubles and sometimes reaches 10-12 thousand rubles. The average service life of the power supply is 5-8 years, and after this period, the battery of the power supply can simply be changed to another one, and the device will serve you for some time.
Types of uninterruptible power supplies
There are three types of uninterruptible power supplies on the market: interactive, backup and online, the latter are used in server rooms, where the requirements for the constancy of the electrical network are very high. In addition to the converter, such devices have inverters and a significant number of control points of the device.
Backup uninterruptible power supplies are mostly low-power devices, they allow you to "survive" a power surge, but they will not cope with the work of organizing a constant power supply to the computer, therefore, most often users purchase devices. which allow you to switch the PC to a backup battery in the event of a power failure in the main network.
Interactive UPSs have voltage stabilizers, they are most suitable for the needs of computers both at home and in the office.
