What is the UPS system? How its work?
UPS ( uninterruptible power supply) systems do two things, one is to give power back up to the equipment and the other is to save from the crisis coming from the power line. A battery bank is attached to the UPS through which it gives electric power when there is no electricity. It also constantly changes the form of electricity coming from the grid, creates a new form, and sends it to the equipment through which the equipment gets controlled and safe electric power and remains protected. Which is called dual conversion in technical language. So the conclusion is installing UPS System is necessary and important to the life of the equipment.
