This modern era is basically based on computer and networking. Mostly, you will find people working on computer wherever you go. If so much of work is being done on computers, it is very essential to have a device that can give little back up to your system in case of sudden power failure.

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.

In case of sudden power failure UPS helps in saving all the open applications, documents and reduces the chances of losing the unsaved data. Additionally, a UPS sets the constant electricity flow into your system saving it from undesirable power surges or spikes when main power returns.

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.

UPS keeps on monitoring the electricity flow and if it discovers a power cut off, it uses its DC charge and gives power to your system by transforming it into AC. This charge can give a backup for approximately 10-15 minutes.

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.

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.
