ON-LINE mode
Upper and lower voltage thresholds within which the UPS can operate
on the automatic bypass in the event of a UPS fault or overload.
Automatic switch controlled by the UPS, used to connect the equipment
directly to the AC-power source.
When AC input power returns following shutdown at the end of the battery
backup time, UPS automatic start can be enabled or disabled.
Time that the connected equipment can operate on battery power.
Device on the front panel indicating the percent remaining backup time
or the percent load.
Internal UPS test on battery status.
See "Start on battery power".
Unit grouping the receptacles for connection to the AC-power source
and the equipment.
A window in a computer program displayed for selection by the user of various
options and parameter settings.
The power supplied to the connected equipment is completely regenerated
by continuous double conversion, i.e. the AC power from the AC-power source
is rectified (AC - DC), then converted back (DC - AC) to AC power.
Devices or systems connected to the UPS output.
Allows a "clean" of computer operating systems depending on the low battery
threshold setting. If the input source is restored during the time period
between the shutdown order and actual system shutdown, it causes a
voluntary interruption of the supply of power to the connected equipment
(lasting 10 seconds) after system shutdown.
Rotary switch controlled by the user, used to connect the equipment directly
to the AC-power source. Transfer of the load to the manual bypass enables
UPS maintenance or replacement, without interrupting the supply of power
to the connected equipment.
The normal UPS operating mode, by which the AC-power source supplies
the UPS, which in turn, following double conversion of the AC power,
supplies the connected equipment.
