Page 32: Working Principle
2.2.2.1 Normal Mode In normal mode, the rectifier converts AC power into DC power. Then the inverter converts DC power into AC output with higher precision and quality. The two Issue 05 (2024-01-30) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 33: Bypass Mode
The bypass power supply is not protected by the UPS and therefore is prone to the mains outage, abnormal AC voltage waveform, or abnormal frequency. Issue 05 (2024-01-30) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 34: Battery Mode
If the mains input is abnormal or the rectifier becomes abnormal, the UPS transfers to battery mode. The power module obtains energy from batteries, and the energy is converted into AC output by the inverter. Issue 05 (2024-01-30) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 35: Maintenance Bypass Mode
2.2.2.4 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 (2024-01-30) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 36: Eco Mode
In either bypass mode or inverter mode, the rectifier is started all the time and charges batteries using a charger. The ECO mode delivers a high efficiency. Issue 05 (2024-01-30) Copyright © Huawei Digital Power Technologies Co., Ltd.
