What will a UPS be used for in a building?

  • A.To provide power to essential equipment
  • B.To monitor building electricity use
  • C.To carry messages between departments
  • D.To control lighting and power systems

Answer: A

A UPS provides power to essential equipment when the mains fails.

An uninterruptible power supply holds a battery and an inverter, and switches over within milliseconds, so servers and medical equipment keep running long enough to be shut down safely or for a generator to start.
