2.2.2.5 ECO Mode
The energy control operation (ECO) mode is an energy-saving mode that can be configured
on the LCD or web user interface (WebUI). In ECO mode, when the bypass input voltage is
within the ECO voltage range, the static bypass switch turns on, and the bypass supplies
power. When the bypass input voltage is outside the ECO voltage range, the UPS transfers
from bypass mode to normal mode. In bypass mode or normal mode, the rectifier keeps
working and charging the batteries using a charger. Using ECO mode provides a higher
efficiency.
