What are the applications of UPS?
In modern society, a constant clean source of power is something that many of us take for granted. The demand for a constant clean power supply is always on an increasing graph. A UPS system is designed to provide constant clean power to any electrical equipment. This is why in recent year’s UPS i.e uninterruptible power supplies have become an ever more important part of both domestic electrical setups and business. The most important first step towards uninterrupted power is to categorize loads into critical, essential and non-essential and then size those that warrant UPS protection in terms of their energy use. • Critical loads are those that the business simply cannot function without like IT infrastructure, routers, networks, servers, and such other things. They will require UPS protection. • Essential loads are those that do not necessarily directly affect business continuity but which may be required for health & safety reasons. These are things such as emergency lighting and heating. They may need UPS protection to ensure their continuity until generator start-up but may not require redundancy. • Non-essential loads can be temporarily lost in a power failure and do not require any form of UPS protection. These are products like canteen, printers, and facilities. They tend to be installed on systems including computers, data centers, and all other sensitive technological equipment. Though all UPS are different they do have two common functionalities: Power Backup – In the event of a complete power failure, a UPS will use a system of batteries to provide power to the critical load. Unlike a standby generator, an uninterruptible power supply is not designed to supply constant backup power in a power failure but is able to provide enough power to shut down the equipment it’s protecting safely. Clean power provision – Power is by definition variable, as such there are often fluctuations in both quality and level of power that is provided through a power grid. There are many types of these fluctuations including sags, surges, and spikes. The UPS system is designed to combat the damaging effects of these fluctuations by acting as a barrier between the equipment and the power supply.
