DaqoXPower 10kV Integrated DC Power Supply System

Daqo Group Co.,Ltd. Stand: M40

KEY BENEFITS

Green and Energy-Efficient: System efficiency is up to 97%, helping reduce operating costs. The rectifier modules maintain high efficiency (≥98%) even at loads between 5% and 60%.

Streamlined Design and Rapid Deployment: The streamlined end-to-end architecture and modular design maximize space utilization, reducing floor-space requirements by more than 50%. The prefabricated design enables rapid manufacturing, standardized assembly, and efficient on-site installation, significantly shortening project delivery times compared with traditional field-built solutions.

Intelligent Digital Management: The system features high-speed data processing and a graphical human-machine interface (HMI). It supports flexible battery grouping in which the batteries are disconnected from the DC busbar. The system is compatible with both lead-acid and lithium batteries and also supports intelligent operations and maintenance (O&M) and smart battery management.

Safety and Reliability: A redundant architecture provides high stability and robust fault protection. Advanced digital current sharing balances load distribution, while high interference immunity supports stable operation. All rectifier modules are hot-swappable.
