What is a UPS?

Put simply, a UPS is a device that:

  • Provides power conditioning and backup power when utility power fails, either long enough for critical equipment to shut down gracefully so that no data is lost, or long enough to keep required loads operational until a secondary AC source, like a generator, comes online.
  • Conditions incoming power so that all-too-common sags and surges don’t damage sensitive electronic gear.
