ECO mode
When the input voltage is within voltage
regulated range, UPS will power the output
directly from the mains. ECO is an
abbreviation of Efficiency Corrective
Optimizer. In this mode, when battery is
fully charged, the fan will stop working for
energy saving.
Buck mode
when AC is
normal.
When the input voltage is higher than the
voltage regulation range but lower than
high loss point, the buck AVR will be
activated.
Boost mode
when AC is
normal.
When the input voltage is lower than the
voltage regulation range but higher than
low loss point, the boost AVR will be
activated.
Battery mode
When the input voltage is beyond the
acceptable range or power failure and
alarm is sounding every 10 seconds, UPS
will backup power from battery.
Standby mode
UPS is powered off and no output supply
power, but still can charge batteries.
