In many offices there are computers that can never be turned off. Machines in which data are stored, which work 24 hours a day and which, in addition to the impossibility of being suddenly without power, cannot even undergo voltage fluctuations. Because? Because a sudden shutdown or power surge could result in loss of data and work for days or weeks.
It is the continuity groups that come to the aid of those who work in a meticulous way. Also known as UPS (Uninterruptible Power Supply) , they are able to power the electrical appliances to which they are connected electrically and without interruption.
Uninterruptible power supplies are obviously not designed only for computers and offices, but also for all those devices that need not to suffer electrical "trauma".
What does an uninterruptible power supply do in a nutshell? It works like a battery, ensuring that, even in critical moments, the appliances never run out of electricity. UPSs, in fact, have lead batteries inside that allow us to sleep peacefully and not realize that normally our power lines have imperceptible voltage changes (for us) but harmful to our electronic devices.
What to know when to buy a UPS? First of all the number of Watts we need, then look at the power supply needs in the event of a power failure, which greatly depends on the number of devices that are attached to the UPS. There are also different types of UPS, with different specific characteristics.
The uninterruptible power supplies for domestic and work use are in fact divided into:
- Offline : they are especially suitable for homes and are especially useful in case of power surges, managing to make up for a power failure for a few minutes.
- Line Interactive : they are those found in offices with multiple locations, they are able to stabilize the voltage through the stabilizer circuit and protect the equipment from blackouts.
