Page 34: Working Principle And Modes
Intelligent control is adopted for modules. The power module consists of a rectifier, inverter, and DC/DC converter. The product converts inputs into pure high-quality sine wave outputs by using the high-frequency switching technology. Issue 02 (2023-11-07) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 35 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 02 (2023-11-07) Copyright © Huawei Digital Power Technologies Co., Ltd.
Page 36 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 02 (2023-11-07) Copyright © Huawei Digital Power Technologies Co., Ltd.
