Automatic Transfer Switch (ATS) is an advanced electrical device designed to automatically transition between dual power sources (main/backup), ensuring a seamless and uninterrupted power supply to vital loads, effectively preventing production halts, data loss, or equipment malfunction due to unforeseen power outages.
- Core functions
Automatic Switching - In the event of a main power supply failure (such as power outage, undervoltage, overvoltage, etc.), it effortlessly transitions to a reliable backup power source (such as generator, UPS, or secondary mains power).
Manual priority mode - Facilitates manual forced switching, allowing for smooth maintenance or urgent interventions.
Zero second switching (optional) - Select models offer seamless, zero-second switching, ideal for environments that demand exceptional power continuity, including data centers and medical equipment.

Fire Alarm Function of ATS
In the sophisticated fire power supply system, the dual power Automatic Transfer Switch (ATS) is indispensable. It seamlessly facilitates automatic switching between the primary and standby power sources. Furthermore, it boasts a robust fire alarm linkage feature, ensuring an uninterrupted power supply to critical fire equipment - such as smoke exhaust fans, fire pumps, and emergency lighting. This functionality is vital during fire emergencies and provides real-time status updates to the fire control center, enhancing safety and reliability.
Forced Switching - Even with the restoration of the main power supply, the backup power source remains operational until manually reset. This is crucial to prevent unintentional power disruptions during firefighting efforts.
High Reliability - Featuring a mechanical/electronic dual interlock system, it effectively prevents the risk of short circuits due to simultaneous connection of two power sources.
Fast Response - Boasting an impressive switching time of ≤ 1 second, and for critical loads, an even faster response of ≤ 0.2 seconds is achievable.
Fire Signal Linkage - Capable of receiving signals from the fire control center and securely locking the backup power source, ensuring utmost safety.
Switch Structure Explained:
1. Electric Key Lock:This ingenious feature controls the internal power supply line of the switch. When the electric lock is open, the switch operates both automatically and remotely. When closed, it can only be manipulated manually.
2. Operating Handle:To operate the switch using the handle, it is essential for the electric lock to be securely closed.
3. Mechanic Padlock:Prior to inspection, turn the switch to the '0' position using the operating handle. Subsequently, engage the padlock mechanism and secure the padlock, allowing inspection arrangements. Engaging the padlock mechanism disconnects the internal control power supply of the switch, ensuring it cannot be in an electric position or operated manually.
4. Position Indication:This denotes the operational status of the switch, indicating positions (I, 0, II).
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Choose a dry and well-ventilated area strategically close to both the main and backup power supply inlets. This positioning ensures seamless operation and simplifies maintenance tasks, enhancing the overall efficiency.
Wiring specifications: Connect your main and backup power supplies carefully to the ATS input terminals. Ensure the output terminal is directly linked to the load, with utmost attention to distinguishing the phase sequence (L1/L2/L3/N/PE) for optimal performance and safety.
Switching test: Conduct a simulation of a main power failure after power-up. Check the automatic switching time, which should typically be within 1.5 seconds, to guarantee uninterrupted load power supply.
Safety requirements: Ensure reliable grounding and match the shell protection level to the environmental conditions (e.g., IP40 for indoor settings). Compliance with the GB/T 14048.11 standard is crucial for safety and reliability.
