Uninterruptible power supply (UPS)

An uninterruptible power supply (UPS) is a device that ensures the safety and operation of critical computer systems, IT equipment, and other electronic devices during power surges and black-outs. A UPS provides immediate backup power from batteries if the power supply drops to insufficient voltage or stops completely.

The main functions of a UPS include:

Backup power: Provides immediate power from batteries, preventing device shutdowns.
Surge protection: Protects devices from sudden voltage spikes that can damage electronics.
Voltage stabilization: Ensures a constant voltage level, enhancing the stability and lifespan of connected devices.

A UPS is essential for maintaining continuous operation of critical systems such as servers, data centers, telecommunications equipment, and other sensitive electronic devices that require reliable power even during electrical black-outs.
