Battery Backup

Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.

Buck/Boost

Full automatic voltage regulation in a UPS stabilizes low voltage (boost) and high voltage (buck) to maintain nominal 120V power without resorting to battery power when minor power fluctuations occur.

Buck

The AVR function of a UPS which reduces voltage when the utility power approaches the high voltage threshold.

Brownout

A drop in voltage for an extended period of time.

Boost

The AVR function of a UPS which increases voltage when the utility power approaches the low voltage threshold.

Blackout

A power failure in which line voltage drops to zero.
