To ensure the normal operation of your computer, as well as the safety of important computer data, it is necessary to use a PC UPS, especially if there are sudden power surges in your home or area.
Modern computer technology is developing for the better every year, however, its power reaches great limits. This is especially noticeable in those regions where the quality of communications is relatively satisfactory. Therefore, many homes have a power problem. And this, in turn, entails a sharp shutdown of the computer, then there is a loss of necessary data or even a breakdown of expensive equipment.
To prevent this, there are special devices, thanks to which you can not worry while using your computer. Such devices include UPS. In other words, this is a special uninterruptible power supply for a computer, a UPS is an uninterruptible power supply.
Types of PC uninterruptible power supply
Uninterrupted devices are of different types, so they were divided into three main groups.
Switchable UPS - the simplest and cheapest model, great for home PCs. Such uninterruptible power supplies are not able to stabilize the voltage, from which we can conclude that this device is more suitable for computers with low power consumption.
Line-interactive uninterruptible power supplies - such models are included in the middle price range. Most often, this type of uninterruptible power supply is used in home or office LANs. In the course of its operation, this model produces stepwise voltage stabilization.
Industrial online UPS - the most powerful UPS, equipped with double voltage conversion technology. We can say that this model belongs to the maximum protection class.
How to choose the right uninterruptible power supply for your PC
When choosing a UPS, you should rely on characteristics such as:
- output power;
- battery life;
- dimensions and design of the device;
- price.
It is best to buy UPS from those stores where the product warranty is given for a period of at least a year. It is also worth noting that you still need to select batteries for the uninterruptible power supply, so the cost in total may be half the declared one.
To choose the most optimal device suitable for all parameters, you need to be guided by the ratio: the nominal load is multiplied by 1, 2. For example, the total power consumption of the computer is 440 W, which means that the minimum power of the UPS should be approximately 630 VA. That is, the power of the UPS must exceed the power of the computer by 20-30%.
