An Offline Uninterruptible Power Supply (UPS) is a device that provides backup power to connected equipment during electrical outages or disturbances. It typically consists of a battery, inverter, and charger, allowing it to convert stored DC power into AC power when needed. Offline UPS systems are designed to switch to battery power almost instantaneously when a power failure is detected, ensuring that sensitive electronics remain operational.
