How disturbing it is to face interrupted power supply when you sit to finish your important presentation or an important project on your computer. Not only, it forces you to restart your computer again and again but also creates the situation where you can tend to lose your important data and files. Hence, in order to combat all such highly disturbing issues at work, mostly people go for reliable, affordable and durable UPS equipments for their computers.

An Uninterruptible Power Supply device stays connected between the power source and your computer. These devices have batteries maintain continuous electrical flow. Unlike standby generators, a UPS provides complete protection from short-lived power disruptions and also offers protection against power surges, brownouts and line noise. The UPS basically comprises of three major components:

•    Rectifier: Post converting the AC power into DC power, rectifier accumulates line power in the battery. This way, power disruption affect the battery charging procedure only as the battery gets charged by the rectifier.

•    Battery: It stores power to support equipment in case of intermittent supply from the source. Also, it determines the duration till when, the UPS will be able to provide power to your equipment.

•    Inverter: Inverter converts the battery DC power into AC power provides nonstop power to the equipment.

Mainly, there are three types of uninterruptible power supply:

•    Online or Double Conversion: It restricts supply fluctuation by maintaining voltage and frequency variations within set limits and continuously supply power from its energy reserves stored in a lead-acid battery.

•    Line Interactive: It stabilizes and regulates voltage fluctuations and on power failure, its bi-directional unit switches to inverter mode to supply battery power.

•    Offline or Passive Standby: Tracks voltage and frequency variations in the mains supply power through its own output and immediately switch from utility power to its own power source on occurrence of power failure.

Cities run on electricity. The more developed the city is, the more is its electricity consumption. Today no company, office, industry can bear the consequences of interruptible power supply. Just a second's break in the electricity supply can result in huge loss. Hence, in order to stay away from this sort of worry and pressure, it is highly advised to procure better systems of UPS so that smooth, 24 hours electricity supply can be maintained.
