Automatic Transfer Switch (ATS)
Available in a diverse range of amperage capacities: 100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A.
Automatic Transfer Switch (ATS) An essential electrical device, the ATS seamlessly transitions between two power sources (main/backup), ensuring uninterrupted power flow to critical loads and safeguarding against production halts, data loss, or equipment harm due to outages.
- Core Functions
Automatic Switching - When the primary power source encounters a failure (including outages, undervoltage, overvoltage, etc.), it effortlessly switches to the backup power source (such as generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual prioritization, allowing forced switching for straightforward maintenance or emergency actions.
Zero Second Switching (Optional) - Select models offer seamless switching for environments demanding exceptional power continuity, like data centers and medical equipment.

Fire Alarm Functionality of ATS
Within the fire power supply ecosystem, the dual power Automatic Transfer Switch (ATS) is indispensable, as it seamlessly transitions between main and backup power sources. It is equipped with a sophisticated fire alarm linkage function that guarantees uninterrupted power for critical fire safety equipment, such as smoke exhaust fans, fire pumps, and emergency lighting. This ensures that, even during a fire, these vital systems remain operational and provide immediate status updates to the fire control center.
Forced Switching Even upon restoration of the main power supply, the backup power remains active until a manual reset is performed. This feature is crucial for preventing inadvertent power outages during fire extinguishing operations.
High Reliability Our ATS boasts a mechanical/electronic dual interlock system. This advanced setup prevents short circuits by ensuring the two power sources are never connected in parallel.
Fast Response The ATS is engineered for rapid switching, completing transitions in ≤ 1 second. For certain critical applications, it achieves a swift response time of ≤ 0.2 seconds.
Fire Signal Linkage The ATS receives signals directly from the fire control center, locking the backup power supply to ensure continuous operation.
Switch Structure Explained:
1. Electric Key Lock:The Electric Key Lock manages the internal control power supply of the switch. When open, the switch allows for automatic and remote operation. When closed, manual operation via the handle is required.
2. Operating Handle:To operate the switch using the handle, ensure the electric lock is securely closed.
3. Mechanic Padlock:For inspections, first set the switch to the '0' position using the handle, engage the padlock mechanism, and secure it with the padlock. This action disconnects the internal control power supply, preventing both electric and manual operation and allowing safe inspection processes.
4. Position Indication:Indicates the operational status of the switch (I, 0, II), providing clear visibility of its current state.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Ensure the ATS is installed in a dry, well-ventilated area. Position it conveniently close to both the primary and auxiliary power supply inlets to facilitate easy operation and hassle-free maintenance.
Wiring specifications: For optimal performance, connect both the main and auxiliary power supplies to the ATS input terminal. The output terminal should be accurately wired to the load, with meticulous attention to the proper phase sequence (L1/L2/L3/N/PE) to ensure smooth functionality.
Switching test: Conduct a simulation of a main power outage once powered on. Verify that the automatic switching is prompt (usually within ≤ 1.5 seconds) and confirm the load remains uninterrupted, ensuring reliable operation.
Safety requirements: Ensure reliable grounding and select a shell protection level suitable for the environment, such as IP40 for indoor settings. All installations should be compliant with the GB/T 14048.11 standard for safety and efficiency.
