Automatic Transfer Switch (ATS) is an advanced electrical device engineered to effortlessly alternate between two distinct power sources (main and backup), ensuring a consistent and reliable power flow to critical systems, effectively preventing any production halts, data loss, or equipment malfunctions that could arise from unforeseen power disruptions.
- Core Functions
Automatic Switching - In the event of primary power supply failures, such as power outages, undervoltage, or overvoltage, it promptly transfers to the backup power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual switching to ensure efficient maintenance or address urgent situations with ease.
Zero Second Switching (Optional) - Select models provide seamless transitions, crucial for high-demand environments requiring uninterrupted power, such as data centers and medical equipment.

This indispensable feature serves to prevent any unexpected outages during crucial firefighting efforts.
Exceptional Reliability: A Benchmark of Excellence - Featuring a dual mechanical and electronic interlock system, this cutting-edge technology prevents short circuits that could arise from the simultaneous connection of dual power sources.
Instantaneous Response: Swift and Sure - With a remarkable switching time of ≤ 1 second, and for some critical loads, an impressive ≤ 0.2 seconds, ensuring minimal disruption in power supply.
Fire Signal Integration: Seamless and Secure - The system adeptly receives and acts upon signals from the fire control center, forcefully securing the backup power supply, enhancing safety.
Comprehensive Switch Structure Explanation: Unlocking the Details
1. Electric Key Lock: Security and Control:This controls the internal power supply lines of the switch. When the electric lock is disengaged, the switch permits automated and remote operations. Conversely, when the electric lock is engaged, manual operation via handle is viable, ensuring flexible control.
2. Operating Handle: Command at Your FingertipsTo operate the switch using the handle, ensure the electric lock is securely engaged, allowing for precise manual control.
3. Mechanic Padlock: Safety in InspectionFor inspection, initially rotate the switch to the '0' position using the handle. Subsequently, secure the padlock mechanism to cut off the switch's internal power supply. This prevents the switch from being in electric mode or manually operated, facilitating safe inspection.
4. Position Indication: Clarity in OperationDisplays the operational status of the switch (I, 0, II) with clarity and precision, offering peace of mind and operational transparency.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location:Select a dry, well-ventilated area that is strategically located near both main and backup power inlets. This ensures seamless operations and facilitates efficient maintenance, crucial for sustained performance.
Wiring specifications: Directly connect the main and backup power supplies to the ATS input terminal, ensuring the output terminal is firmly connected to the load. Pay meticulous attention to accurately distinguish the L1, L2, L3, N, and PE phase sequence, as this is essential for optimal performance and safety.
Switching test: Once powered, simulate a main power failure to conduct a system test. Confirm the system's impressive automatic switching speed (typically ≤ 1.5s), ensuring the load remains uninterrupted and fully functional.
Safety requirements: Ensure robust grounding of the system, with the shell's protection level tailored to the environmental conditions (such as IP40 for indoor installations). Adhering to the GB/T 14048.11 standard is imperative for compliance and safety assurance.
