Operating Mode Description
LCD Panel
ECO (Efficiency
Corrective
Optimizer) Mode
When the input voltage is within the voltage
regulated range, the UPS powers the output directly
from the mains. When the battery is fully charged in
this mode, the fan stops working to save energy.
Buck Mode
(When AC is
normal)
When the input voltage is higher than the voltage
regulation range, but lower than the high loss point,
the buck AVR (automatic voltage regulation) is
activated.
