2.2.2.5 ECO Mode
The economic control operation (ECO) mode is an economical working mode,
which can be
congured on the LCD or web user interface (WebUI). In ECO mode,
when the bypass input is within the ECO voltage and frequency ranges and other
ECO power supply conditions are met, the UPS works in bypass mode and the
inverter is in standby state. When the bypass source voltage is outside the ECO
voltage range, the UPS transfers from bypass mode to inverter mode. In bypass
mode or normal mode, the
rectier keeps working and charges batteries using a
charger. The ECO mode delivers a high
eciency.
