Output capacity 1200 kVA Solution FusionPower The maximum capacity of UPS5000-S-1200 kVA-FP is 1200 kVA and it is compatible with a capacity of 1100 kVA, 990 kVA, 880 kVA, 770 kVA and 660 kVA. 2.2 Working Principle  indicates an input mode.
Page 21: Conceptual Diagram
In normal mode, the rectifier converts AC power into DC power, then the inverter converts DC power into high-precision AC outputs. The conversions protect loads from interference such as input harmonics, glitches, and voltage transients. Issue 04 (2019-06-25) Copyright © Huawei Technologies Co., Ltd.
Page 22: Bypass Mode
UPS which means it may be affected by mains outage, and incorrect AC voltage or frequency. Figure 2-4 UPS conceptual diagram in bypass mode Issue 04 (2019-06-25) Copyright © Huawei Technologies Co., Ltd.
Page 23: Battery Mode
The maintenance bypass unit has been installed. When the UPS works in maintenance bypass mode, the current flows through the maintenance bypass instead of the power module. You can maintain the circuit inside the cabinet. Issue 04 (2019-06-25) Copyright © Huawei Technologies Co., Ltd.
Page 24: Eco Mode
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 high efficiency. Issue 04 (2019-06-25) Copyright © Huawei Technologies Co., Ltd.
Page 25: Joint Power Mode
In this case, the power module obtains energy from both the mains and batteries, and the energy is converted into AC outputs over the inverter. Figure 2-8 Conceptual diagram in joint power mode Issue 04 (2019-06-25) Copyright © Huawei Technologies Co., Ltd.
