In this period of computer and technology when most of the work has been shifted to computers, it is very important to have a equipment which can provide back up to various computers during power cut off.
This backup can be provided by Uninterruptible Power Supply (UPS). The battery used in a UPS provide backup to the system after power failure. This battery should be kept charged so that it can help during power cut off and enable us to shut down the system as it should be done to add years to its circuit.
Many times we have seen people shouting like I lost all my important data. It is all because of the reason that he has not saved the document and there is a sudden power cut off. The best equipment that can help him in this scenario is a UPS, it also save your system from ups and downs of electricity flow.
A UPS is an intermediate between the computer and main power supply. A computer is connected to UPS which is further connected to main supply. A typical UPS contains a battery charger for lead acidic battery, DC to AC converter and a surge suppressor.
Whenever there is a power failure or power fluctuation, UPS starts its working. In case of power failure it uses its DC charge, changes it to AC and gives continuous backup of 10-15 minutes to your PC.
There are basically three types of UPS, Offline Standby, Online and Line Interactive. An Offline Standby UPS is very efficient and less expensive and it behaves like a surge suppressor until main power is broken. In this little or no line conditioning is required. Additionally, battery backup starts on electricity fluctuation.
The second type that is Online UPS sets constant electricity flow and UPS starts immediately after power breakdown, but it is expensive to buy. Third one that is Line-Interactive UPS is quite much like Standby UPS along with multi-tap variable-voltage auto transformer feature. Without using reserve battery power, it can bear nonstop voltage surges.
Unit used to calculate the load size of a UPS is VA (Voltage*Amp). A UPS load should never surpass 60 percent of mentioned VA. Therefore, we can say that UPS solves our problem on power failure, voltage up and down, frequency variation etc.
