The term functions as an acronym, standing for Uninterruptible Power Supply, which describes a hardware device that provides emergency power to a load when the primary power source fails. IT professionals must calculate the total power consumption of the equipment to determine the appropriate capacity, measured in Volt-Amps (VA) or Watts.

The unit constantly monitors the incoming power, and only switches to battery power when it detects an anomaly, such as a surge or outage. This seamless transition, which typically occurs in less than 10 milliseconds, prevents computers and servers from shutting down unexpectedly, thereby safeguarding data integrity and preventing hardware damage caused by sudden power loss.
The battery is always online and charging, meaning there is zero transfer time. The rectifier converts incoming alternating current (AC) to direct current (DC) to charge the internal batteries.
