Industrial Control Circuits & UPS Systems Quiz

An Online UPS, also known as a Double Conversion UPS, is a type of UPS system that constantly processes electrical power through its inverter, regardless of whether the input power is stable or not.

An Offline UPS, also known as a Standby UPS, is a type of UPS system that only activates its inverter and battery when it detects a power interruption or voltage outside a predefined acceptable range.

The transfer time, sometimes also called switchover time, is the amount of time the UPS will take to switch from utility to battery supply during a mains failure, or from battery to mains when normal utility power is restored.
