What is UPS?

A UPS (Uninterruptible Power Supply) is a backup power device that provides immediate electricity when the main power supply fails. It contains a battery, inverter, and control circuitry that ensure connected equipment continues to operate without interruption. UPS systems are commonly used for computers, servers, medical devices, security systems, and networking equipment. They also help regulate voltage by filtering spikes, surges, and electrical noise, protecting sensitive electronics.

A UPS helps to prevent data loss and system crashes during power cuts or fluctuations by maintaining an alternative supply of energy. It gives users enough time to save work and shut down devices safely. Users can also choose to continue operation in critical situations that have to be completed in one go, if they can be completed before UPS runs dry.
