Page 22: Working Modes
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 05 (2018-01-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
Page 23: Bypass Mode
The bypass power supply is not protected by the UPS which means it may be affected by mains outage, and incorrect AC voltage or frequency. Issue 05 (2018-01-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
Page 24: Battery Mode
If the mains input is abnormal or the rectifier becomes abnormal, the UPS transfers to battery mode. The power module obtains DC power from batteries, and the power is converted into AC output by the inverter. Issue 05 (2018-01-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
Page 25: Maintenance Bypass Mode
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 05 (2018-01-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
Page 26: 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 05 (2018-01-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
