2.2.2.5 ECO Mode
The ECO mode is an economical working mode, which can be
congured on the
user interface. 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 either bypass mode or inverter mode, the
rectier is started all
the time and charges batteries using a charger. The ECO mode delivers a high
eciency.
