As far as the requirement of power protection systems is concerned, the name of UPS or uninterruptible power supplies always comes first in mind. It is one of the best sources of immediate and emergency power backup for certain period of time in case of sudden power loss. Depending on the power load and use, a UPS system can keep the power supply continuous for a few minutes to hours.
However , uninterruptible power supplies are available in different power loads from 350VA to 6MVA. However, for mission critical operations, feeding servers, data centres and other critical devices, they are also available in 10 VA to 12 VA. No doubt, there are the power protection devices that also perform a number of other functions like surge protection, voltage stability, power fluctuation levelling and a number of others. It is a fact that uninterruptible power supplies are very helpful in handling surge intercepts.
Apart from this, a UPS system also keeps the voltage supply maintained at a constant level. It in case of low voltage boost the voltage level; while lower the high voltage to provide uninterrupted power supply. The process of voltage maintenance is done through the batteries. Uninterruptible power supplies also ensure steady source of power supply to all the attached electrical equipments as well as they also handle the deficiencies of power grid. In addition the aforementioned functions, UPS systems also provide protection from the line transients, suppressing transverse mode noise and harmonic disruptions as well.
If you spend a good time over computer to finish a number of important works, then having a UPS system is very vital. This is because; a power fluctuation less than a few microseconds can turn into a major loss as you may loss important data or hard-disk may crash. While, UPS systems provide you enough time to shut down your computer by saving or transferring important data or at least shift the power load to other alternatives like generators.
Depending on your requirement, power load and budget, different types of uninterruptible power supplies are available in the market like On-line, Off-Line. Double-conversion and delta-conversion as well.
