Page 25: Working Principle
Its power module consists of a rectifier and inverter. The UPS5000 converts inputs into pure, high-quality sine wave outputs by using the high-frequency switching technology. Figure 2-2 Conceptual diagram in air cooled scenario Issue 09 (2019-12-20) Copyright © Huawei Technologies Co., Ltd.
Page 26: Working Modes
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 09 (2019-12-20) Copyright © Huawei Technologies Co., Ltd.
Page 27: 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 09 (2019-12-20) Copyright © Huawei Technologies Co., Ltd.
Page 28: 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 09 (2019-12-20) Copyright © Huawei Technologies Co., Ltd.
Page 29: 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 09 (2019-12-20) Copyright © Huawei Technologies Co., Ltd.
