First, we start with the definition of the abbreviation UPS as an uninterrupted power supply. A UPS contains a battery that “kicks in” when the device senses a loss of power from the primary source. If a computer user is working on the computer when the UPS notifies power loss, they have just enough time to save any data they are working on and exit before the secondary power source (the UPS battery) runs out leaving them seriously stranded.
Below are principles on how the UPS works, There are two common systems in use today: standby UPS and continuous UPS.
A standby UPS runs the computer off of the normal utility power until it detects a power loss.
At this particular point, it happens very quickly (in five milliseconds or less) which will automatically turn on a power inverter and run the computer off of the UPS’s battery. A UPS as a power supply depends on another battery source, so the UPS, therefore, makes use of a battery. A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components to enable function.
These batteries are mostly used in UPS, Plante battery, calcium battery, antimony battery, calcium liquid-free electrolyte battery.
Average battery voltage means “voltage” in a battery difference in electrical potential between the positive and negative terminals of a battery line.
There seems to be two different types of UPSs namely the On-line UPS and the Standby UPS.
