Eco mode

If economical (ECO) mode is selected, the double conversion UPS will stop to work so as to save energy. During the operation of ECO mode, the load power will be supplied by bypass preferentially. When bypass power is within the range of normal frequency and voltage, load power will be supplied by bypass, or the system will transfer to inverter input, followed by load power interruption which extends within 3 4 of the utility period. E.g. when the frequency is 50Hz, the interruption time will be less than 15ms; when the frequency is 60Hz, the time will be less than 12.5ms.
