What does an Uninterrupted Power Supply actually do?
The general perception is that an Uninterrupted Power Supply provides power to an electrical device in case there’s a blackout, and that’s the only function people attribute to it. But, the UPS performs several other functions. It not only powers the device when there’s a power failure, but it can also keep the voltage difference across the device at a constant rate. That means, if there is an unexpected fall in the current flowing into the device or, for that matter, even an unexpected surge, the UPS will take care that the voltage difference across the device is still maintained constantly. For sensitive devices like computers and air conditioners, this is a very important benefit. If you think by the principle of working, anything that provides an unhindered power supply to an electrical device can be called as an UPS. Indeed, some professionals even call the small 9 volt batteries that are used as backups for less power-consuming electrical devices as UPS systems. At the same time,
