Answer Posted / Ujjwal Kumar
Online UPS (Uninterruptible Power Supply) refers to a power system that provides continuous electrical power to a load when the input power source, typically the main electricity supply, fails. It uses battery backup and automatically switches to battery power within milliseconds of a power failure. Offline UPS, on the other hand, only supplies clean battery power for a short period (10-20 minutes) after an outage to allow for a safe and orderly shutdown of equipment.
