Uninterruptible Power Supply (UPS)

An uninterruptible power supply, or UPS for short, is an electrical device that provides emergency power to a load when the main power source fails. This consists of a battery backup system that supplies power instantly or with minimal delay, ensuring continuous operation of connected equipment. Some UPS units can also protect against power surges, voltage drops, and other electrical irregularities, making it essential for critical systems like computers, data centers, and medical equipment.
