    Overview 2.5.5. ECO Mode ECO mode is an UPS energy-saving mode which can be set through the LCD or background software. In ECO mode, when the bypass input voltage is within the ECO range, the load is powered by utility through bypass static switch, the rectifier and inverter are standby. When the bypass input voltage exceeds the ECO voltage range, the load will be switched from the bypass power supply to the inverter power supply, and the UPS will work in normal mode.
