Page 33: Working Principle
2.3.1 Normal Mode The normal mode indicates that the UPS works normally: The rectifier converts the AC input voltage into the DC voltage, which is then raised to the bus voltage Issue 17 (2024-02-21) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 34: Bypass Mode
The power supply in bypass mode is not protected by the UPS and therefore tends to be affected by the mains outage and abnormal AC voltage waveform or frequency. Figure 2-4 Bypass mode Issue 17 (2024-02-21) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 35: Battery Mode
2.3.5 ECO Mode The economic control operation (ECO) mode is an energy-saving mode, which you can configure on the liquid crystal display (LCD) or web user interface (WebUI). In Issue 17 (2024-02-21) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 36: Chassis Description
In either bypass mode or normal mode, the rectifier keeps working and charges batteries over a charger. The ECO mode guarantees high efficiency. Figure 2-7 ECO mode 2.4 Chassis Description Issue 17 (2024-02-21) Copyright © Huawei Digital Power Technologies Co., Ltd.
