Uninterruptible power supplies are ideal solutions for businesses that require constant power, even in the case of blackouts. Unlike standby generators or other backup power supplies, UPSs provide near instantaneous protection from input power interruptions by supplying energy stored in batteries, supercapacitors or flywheels. UPSs are typically used to protect hardware such as computers, data centres and telecommunications equipment, as well as any other electrical equipment where an unexpected power disruption could cause injuries, serious business disruption, or data loss.
