It's always annoying when the power goes out, especially when you're working on a computer. The fact that the light goes out and you are in the dark is the least annoying thing. If your computer stops working, it is much worse, because you run the risk of losing data and damaging the operating system. This can be prevented with a UPS, a provision for emergency power. This ensures that your computer(s) continue to work for some time. This gives you ample opportunity to save your files and shut down the computer in a normal, safe manner.
Especially for companies
Companies can suffer a lot of damage if computers and servers suddenly lose power, but production machines can also break down if they crash during a power outage. Such risks are much smaller with a provision for emergency power. It almost always consists of a unit and a battery. If the mains voltage fails, the device immediately switches to 220 volt alternating current supplied by the battery. The capacity of the battery and the power of the connected computers and/or production machines together determine how long this equipment will continue to function. It is recommended to choose a battery with sufficient capacity for at least 10 minutes.
Types of facilities
There are three different types of solutions for emergency power or Uninterruptable Power Supplies, each with their own characteristics. Online and line-interactive systems are always connected to 230 volts. Standby systems only switch on when the mains power fails. Which solution you choose depends mainly on the vulnerability of the equipment you want to connect to it. Online systems do more than just deal with power outages. They also protect your equipment against voltage spikes. The other two types of solutions do not.
Online solutions for emergency power
Online facilities have two converters. The first transforms the 230 volt mains voltage down to direct current. On the one hand, this direct current is used to charge the built-in battery. The direct current also feeds the second converter, which transforms the direct current back into interference-free alternating voltage of 230 volts, on which all connected equipment runs. As soon as the mains power fails, the direct current from the battery serves as a source for the second converter. In this system, the power outage is absorbed without a dip in the voltage supply.
Line interactive and standby UPS
A line-interactive system has only one converter. The connected equipment is normally directly connected to the mains voltage. The battery is only switched to with a converter to 230 volt alternating current if there is a power failure. That is very similar to a standby system. The biggest difference with a line-interactive system is that standby systems use separate batteries. With both of these solutions, there is a dip in the power supply for a fraction of a second in the event of a power failure. That usually doesn't cause any problems.
For at home
At home you also want to protect vulnerable equipment against power outages, but this can be done with simpler solutions for emergency power. Many people work at home with a laptop. If the power goes out, the internal battery will take care of it. This allows you to save your files and shut down the laptop normally. This also applies to a smartphone, but it can run out of power. Then it is nice if you have some spare power. This is possible with a power bank. This allows you to charge your smartphone a number of times. Even if the power outage lasts for a longer period of time, you can still be reached with the help of a power bank.
