Line Conditioners
Line conditioners are designed to maintain AC voltage at a fairly constant level.
Uninterruptible Power Supplies
A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that provides temporary power to connected devices when AC
power is interrupted. The battery charges while AC power is available. See the UPS manufacturer documentation for information on battery operating time and
to ensure that the device is approved by Underwriters Laboratories (UL).
NOTICE:
Line conditioners do not protect against power interruptions.
NOTICE:
Loss of power while data is being saved to the hard drive may result in data loss or file damage.
NOTE:
To ensure maximum battery operating time, connect only your computer to a UPS. Connect other devices, such as a printer, to a separate power
strip that provides surge protection.
