An Uninterruptible Power Supply (UPS) is a device that provides emergency power to a load when the input power source or mains power fails. A UPS protects electronic equipment such as computers, servers, networking hardware, and other devices where an unexpected power disruption could cause data loss, hardware damage, or downtime. UPS systems typically incorporate a battery backup to ensure continuous power supply during outages, voltage fluctuations, or other power-related issues.
