Uninterruptible Power Supply Requirements
An uninterruptible power supply (UPS) is a device that sits between a power supply (such as a wall
outlet) and a device (such as a switch) to prevent outages, sags, surges, and bad harmonics from
adversely affecting the performance of the device.
A UPS traditionally can perform the following functions:
Absorb relatively small power surges.
●
Smooth out noisy power sources.
●
Continue to provide power to equipment during line sags.
●
Provide power for a period of time after a blackout has occurred.
