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.
A UPS (Uninterruptible Power Supply) can provide good back up to your PC, and save its life. A UPS is a battery backed equipment that enables your system to operate for short duration even after main power has stopped. It also enables you to systematically shutdown your PC.
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.
A UPS continuously detects the flow of electricity and whenever it detects a drop in electricity, it converts its DC charge to AC and provides power to your computer for around 10-15 minutes.
We will now talk about the different types of UPS that we can use. Offline Standby, Online and Line Interactive are the three types of UPS used generally. Offline standby is not only economical but it is also very efficient. It performs like a surge suppressor when main supply is on and starts battery backup whenever there is fluctuation in electricity.
When you will use Online UPS, you will not find any delay in between power outage and UPS starting. It is little costly but delivers continuous and invariable flow of electricity. However, Line Interactive UPS is similar to Standby UPS and tolerates under voltage and over voltage easily. It also has an extra multi-tap variable-voltage auto transformer in it.
To find out the amount of load a UPS can bear VA (Voltage*Amp) is used. It can not bear a load beyond 60% of stated VA. UPS is useful during power failures, voltage drop, voltage spike, line noise, frequency deviation, harmonic distortion etc.
