2.2.2.5 ECO Mode
The economy control operation (ECO) mode is an energy-saving mode, which you can
configure on the liquid crystal display (LCD) or web user interface (WebUI). In ECO mode,
when the bypass input voltage is within the ECO voltage range, the bypass combined switch
turns on, and the bypass supplies power. When the bypass input voltage is beyond the ECO
voltage range, the UPS transfers from bypass mode to normal mode. In bypass mode or
normal mode, the rectifier keeps working and charges batteries using a charger. The ECO
mode delivers a higher efficiency.
