Automatic Transfer Switch (ATS) is an advanced electrical device engineered to seamlessly switch between two power sources (main/backup), ensuring an uninterrupted power supply to critical loads, thus preventing any production downtime, data loss, or potential equipment damage due to unforeseen power outages.
-Core functions
Automatic Switching - During a main power failure, whether it's a power outage, undervoltage, or overvoltage, the system swiftly transitions to the backup power source (such as a generator, UPS, or secondary mains power).
Manual priority mode - enables manual forced switching to facilitate efficient maintenance or urgent operations with ease.
Zero second switching (optional) - Selected models offer seamless, zero-second switching, ideal for environments demanding exceptional power continuity, such as data centers and medical equipment.

Fire Alarm Function of ATS
In the fire power supply system, the dual power automatic transfer switch (ATS) is engineered to not only seamlessly switch between the main and backup power sources but also integrates a sophisticated fire alarm linkage function. This ensures the unwavering power supply for essential fire equipment-such as smoke exhaust fans, fire pumps, and emergency lighting-in the event of a fire. Furthermore, it provides instantaneous feedback to the fire control center regarding the operational status, enhancing safety and reliability.
Forced Switching - Even when the main power supply is restored, the backup power continues to operate until manually reset. This is crucial to prevent accidental power outages during critical fire extinguishing operations, ensuring uninterrupted safety.
High Reliability - Features a sophisticated mechanical/electronic dual interlock system to effectively prevent short circuits that could arise from the parallel connection of two power sources, bolstering system integrity.
Fast Response - The switch guarantees a rapid switching time of ≤ 1 second, with certain critical loads demanding an even swifter response at ≤ 0.2 seconds, catering to high-demand environments.
Fire Signal Linkage - Upon receiving signals from the fire control center, the system forcibly locks onto the backup power supply, ensuring safety and operational integrity during emergencies.
Switch Structure Explanation:
1. Electric Key Lock:This mechanism governs the internal control line power supply of the switch. When the electric lock is open, the switch can be operated both automatically and remotely. Conversely, when the electric lock is closed, it can only be operated manually using the handle, providing a secure operation protocol.
2. Operating Handle:To operate the switch using the handle, the electric lock must be secured. This ensures that operations are conducted with deliberate intent, enhancing operational safety.
3. Mechanic Padlock:During inspections, first turn the switch to the '0' position using the operating handle. Then, engage the padlock mechanism and secure the padlock to commence inspection. Engaging the padlock will cut off the internal control power supply, rendering the switch inoperative both electrically and manually, ensuring a safe inspection environment.
4. Position Indication:This feature denotes the operational position of the switch, indicating its status as I, 0, or II, providing clear visual confirmation of the switch's current state.
Installation Instructions
Installation Method of Dual Power Automatic Transfer Switch (ATS):
Installation Location: Position the ATS in a dry, well-ventilated area, strategically located near both primary and backup power sources. This facilitates seamless operations and simplifies maintenance.
Wiring Specifications: Connect the primary and backup power sources to the ATS input terminals. The output terminal should be linked to the load, with strict adherence to the phase sequence: L1, L2, L3, N, and PE. This meticulous setup ensures optimal performance.
Switching Test: Conduct a simulated main power outage once the system is powered on. Verify the automatic switching capability, ensuring it occurs within a rapid timeframe (typically ≤ 1.5 seconds) and confirm that the load remains consistently active without power interruption.
Safety Requirements: Ensure robust grounding and that the enclosure protection level is aptly suited for the environmental conditions (e.g., IP40 for indoor use). Additionally, compliance with the GB/T 14048.11 standard is mandatory to guarantee safety.
