An AC uninterruptible power supply (UPS) is a device that provides emergency electrical power to connected loads when the main power supply fails. It typically uses batteries or supercapacitors to store energy and delivers it immediately to prevent disruptions.Key points about UPS include:Types: There are different types of UPS, including standby (offline), line-interactive, and online (double-conversion) UPS1.Functionality: UPS systems protect against power issues like outages, voltage drops, and surges, ensuring critical devices remain operational3.Applications: They are commonly used in data centers, hospitals, and other critical environments where power continuity is essential4.For more detailed information, you can refer to sources likeand.
