What is a UPS
Uninterruptible Power Systems or UPS allow you to continue using a computer equipment when there is a voltage drop in the network
All computer components they require electricity to function. In Spain the supply is very good and there are rarely casual cuts, usually maintenance. But not all over the world electricity is so stable. For To avoid the loss of information or that the components can be damaged are the Uninterruptible Power Supplies or UPS.
What is a UPS
It is a device that stores energy and allows an electronic device to be kept on for a certain time. Uninterruptible Power Systems in computing are used to prevent loss or corruption of data and damage to equipment. A UPS can supply power for a certain time which is given by the capacity of the internal batteries.
Internally, a UPS, as we said, has a battery and a series of electronic circuits. The batteries are charged from the home or local electrical network through a circuit that converts it from alternating to continuous. If there is a power outage, there is another circuit that turns it into AC at the appropriate frequency.
The simplest UPSs are usually backup and little else. A quality UPS can do other functions that may be interesting. UPSs can protect equipment against specific voltage peaks or eliminate noise in the voltage.
Some modern UPSs add the filtering option for internet connections. Note that this causes a loss in the signal, reducing the speed of the connection. There are also those with USB ports to power smartphones, tablets, etc.
What is a UPS for
The Uninterruptible Power Systems serve as backup against power outages. They allow us for a short period of time to use computer equipment and save vital information and shut down the system. These devices are not intended for long-term supply..
Another utility of UPSs is to avoid system outages due to a small voltage drop make it temporary. Some have the ability to absorb small power surges.
Unfortunately the Uninterruptible Power Supplies do not protect against prolonged power surges, only transients (few milliseconds). If lightning strikes our power grid, the UPS will do nothing, as it will not be able to absorb as much electrical power.
In short, a UPS only serves to avoid the loss of critical data when there is a voltage drop in the network. It can protect against micro-cuts or small power surges, but little else.
