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.

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.

If you do not have a UPS, go today only and buy a new UPS and attach it to your computer to stay away from the risk of losing data. Besides a lead acidic battery, a UPS also have a 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.

Various kinds of UPS are available in the market like Offline Standby, Online and Line Interactive. Offline Standby is effective, cheap and acts like a surge suppressor when main power supply is there. Backup starts during fluctuation of electricity and it does not need line conditioning.

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.

The load size that a UPS can easily handle is determined in VA (Voltage*Amp) rating. Thumb rule states that UPS load should never exceed 60 percent of its stated VA. Hence a UPS helps in case of power failure, voltage sag, voltage spike, under-voltage, over-voltage, line noise, frequency variation, switching transient and harmonic distortion.
