1.3. SYSTEM DESCRIPTION
1.3.1 Modes of Operation
The
UPS is designed to operate as a line interactive uninterruptible power supply
in the following modes:
A. Normal - In
normal operation incoming AC power is fed to the input, conditioned and applied
to the connected equipment. In this mode, power is also derived from utility
power for the battery charger. In the event of a utility outage or severe
abnormality (sag or swell), the UPS will support the connected load from
battery power, until the battery is discharged or the utility returns;
whichever occurs first.
B. Battery - Upon
failure of utility / mains AC power, the critical AC load is supplied by the
battery. The switch over time to battery is less then 2 milliseconds.
C. Recharge - Upon
restoration of utility / mains AC power, after a utility / mains AC power
outage, the input converter automatically restarts and resumes supplying power
to the connected load and the battery charger to recharge the battery.
D. Automatic Restart -
Upon restoration of utility / mains AC power the UPS automatically restarts and
assumes supplying power to the critical load and the battery charger.
