What is a UPS?
“An uninterruptible power supply [or system] is defined as a
back-up power system used to ensure uninterrupted power for
various electronic devices.”

Uninterrupted power may be achieved in the following ways:
• Provides back-up power when utility power fails
• Either long enough for critical equipment to shut down sequentially, ensuring
no data is lost, or
• Long enough to operate required loads before a generator comes on-line
• Provides clean and regulated power to electronic devices
