Use uninterruptible power supply for unstable voltage

What is an uninterruptible power supply (UPS) system?

Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.

Why do we need uninterruptible power supplies?

However, during transmission and distribution, it is subject to voltage sags, spikes and outages that can disrupt computer operations, cause data loss and damage equipment. The uninterruptible power supplies protect the connected equipment from power problems and provide battery backup during power outages.

How do uninterruptible power supplies (UPS) mitigate voltage sags?

Uninterruptible power supplies (UPS) mitigate voltage sags by supplying the load using stored energy. Upon detection of a voltage sag, the load is transferred from the mains supply to the UPS.

Why do you need a rechargeable battery for a UPS system?

David G. Dorrell UPS systems are used to provide reliable and uninterruptible power for critical loads by transferring power supply from the utility to backup energy storage when a power disruption occurs. Rechargeable batteries are always the primary choice owing to their comparatively high energy density.
