Technology and Application of QYQ Dual Power Automatic Transfer Switch

In modern buildings and industrial infrastructure, the reliability of the power system is directly related to the normal operation of equipment and the safety of personnel. For critical places such as hospitals, data centers, rail transit, and financial systems, once power supply is interrupted, it will not only cause economic losses, but may also trigger serious safety accidents. To address this challenge, Zhongxin Qiaoyu Electric Technology (Suzhou) Co., Ltd. has launched the QYQ Series Dual Power Automatic Transfer Switch, providing fast switching and stable guarantee for critical power usage scenarios.

Technical Principle —— Completing Power Switching in Milliseconds

The QYQ series Dual Power Automatic Transfer Switch (Automatic Transfer Switch, ATS) monitors parameters such as voltage, frequency, and phase sequence of two power sources in real-time. When it detects faults such as under-voltage, over-voltage, phase loss, or power failure in the main power source, it automatically switches the power supply to the backup power source.

Core features include:

• Fast Switching: Completes power transfer at the millisecond level, avoiding equipment restart or data loss caused by power outage.
• Status Indication and Remote Control: Some models support real-time status display and can link with smart power systems to achieve remote switching and operation and maintenance management.
• Anti-Backfeed Function: Ensures that reverse power supply will not occur between different power sources, avoiding safety accidents.

Product Advantages —— Stable, Durable, Intelligent

1. High Reliability Mechanical and Electrical Life: Uses wear-resistant alloy contacts and optimized drive structure to ensure long-term operational stability.
2. Precise Detection and Rapid Response: Advanced sensing and control modules accurately identify power abnormalities and respond quickly.
3. Intelligent Extension: Optional communication modules can access smart power platforms, supporting networked management and global operation and maintenance.
4. Multiple Installation Methods: Cabinet, panel, or independent installation are all available, meeting the needs of different engineering sites.
5. Complies with National Standards: All models have passed CCC certification and related test reports, ensuring compliance for engineering applications.

Application Scenarios —— Guardian of Critical Power Supply Continuity

• Medical Institutions: Ensures stable power supply for medical equipment in critical areas such as operating rooms and ICUs.
• Data Centers and Communication Rooms: Ensures seamless switching of servers and communication equipment to backup power when mains power fails.
• Rail Transit: Provides stable operation guarantee for signal control systems and track lighting.
• Commercial Complexes: Whether emergency lighting or important commercial equipment, can switch immediately during power supply failures, ensuring operational continuity.
• Industrial Production Lines: In automated production and precision machining, avoids process waste and equipment damage caused by momentary power outages.

Synergy with Zhongxin Qiaoyu Smart Power Solutions

In the smart power system, the QYQ series dual power switch is not only an independent power supply protection device, but can also form a complete safe and stable power supply system with electrical fire detectors, surge protectors and other products. Through unified platform monitoring and data collection, operation and maintenance personnel can monitor power status in real-time and intervene before abnormalities occur, achieving "globally visible, preventable risks" power supply management.

Conclusion

Power supply continuity is the cornerstone of modern society's operation, and the dual power automatic transfer switch is a key node on this cornerstone. Zhongxin Qiaoyu's QYQ series products, with advantages such as fast response, stable durability, and intelligent expansion, have been applied in multiple national key projects and high-standard power projects. In the future, with the advancement of smart cities and Industry 4.0, the QYQ series will continue to serve as the backbone of power supply stability, ensuring every kilowatt-hour of electricity arrives safely.
