1.Selective Switching: Enables users to switch between two power sources as needed, enhancing operational flexibility.
2.Safety and Protection: Provides comprehensive protection against short-circuit, overload, under-voltage, and loss of voltage, ensuring safety in power supply systems.
3.Fire Protection Compliance: Suitable for environments that require fire safety compliance, such as office buildings, hospitals, and shopping malls.
4.Long Service Life: Designed for durability and reliability, resulting in a longer operational lifespan.
5.Quiet Operation: The single-motor drive mechanism ensures smooth and noise-free operation with minimal impact force.
1. Normal Main Power State:When the main power supply is functioning normally and the function switch is set to the automatic position, the standby circuit breaker opens while the main circuit breaker closes. This ensures that the main power supply is connected to the load.
2. Voltage Interruption Detection:If there is a voltage interruption in one or all three phases of the main power supply, the Automatic Transfer Switch (ATS) detects this abnormal condition.
3. Load Transfer:The ATS transfers the load from the main power supply to the standby power supply, provided that the standby power supply has normal voltage available.
4. Power Restoration:Once the main power supply returns to normal voltage levels, the ATS automatically switches the load back from the standby power supply to the main power supply.
5.Key Functions
Automatic Switching: Ensures seamless load transfer based on the status of the power supply to maintain continuous operation.
Real-Time Monitoring: Continuously monitors the voltage of the power supply to ensure system stability and safety.

4.Vibration and Shock Resistance: Passes mechanical vibration and shock tests, suitable for environments like server rooms and workshops.
1.Fully Automated Assembly Line: Key processes such as motor assembly, contact welding, and controller testing are automated.
2.Dual Functional Testing: Each unit undergoes electrical performance tests and mechanical linkage tests.
3.Strict Quality Control: Implements ISO 9001 quality management system with 100% inspection of critical components.
4.Traceability Management System: Each product has a unique serial number for full-process traceability.
1. Does it support switching between generator and grid power?
Yes, can be set to grid priority or generator priority mode with adjustable switching time.
2. Is there a power interruption during switching?
Break-before-make design results in a brief interruption, typically ≤100ms.
3. Does it support remote monitoring?
Optional communication modules support remote status monitoring and control.
4. What are the phase sequence requirements during installation?
Main and backup power phase sequences must be identical; otherwise, switching may fail or cause equipment damage.
