Automatic Transfer Switch (ATS)
100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A
Automatic Transfer Switch (ATS) is an essential electrical device designed to automatically switch between two power sources (main/backup), ensuring an uninterrupted power supply to critical operations and preventing costly production interruptions, data losses, or equipment damage due to unexpected power outages.
- Core Functions
Automatic Switching - Seamlessly transitions to the backup power supply when the main source fails due to power outage, undervoltage, overvoltage, etc. (such as generator, UPS, or secondary mains power).
Manual Priority Mode - Allows user-directed switching for straightforward maintenance or urgent operational needs.
Zero Second Switching (Optional) - Certain models feature seamless switching capabilities, perfect for environments demanding absolute power consistency, such as data centers and medical equipment.

Fire alarm function of ATS
In the sophisticated realm of fire power supply systems, the dual power automatic transfer switch (ATS) plays a pivotal role. It not only seamlessly orchestrates the automatic transition between primary and auxiliary power sources but also boasts an essential fire alarm linkage capability. This ensures an uninterrupted power supply to vital fire safety equipment, such as exhaust fans, pumps, and emergency lighting, during fire emergencies. Moreover, it provides instantaneous status updates to the fire control center, enhancing both safety and responsiveness.
Forced Switching - Even when the primary power source is restored, the secondary power is retained until a manual reset is performed, safeguarding against unexpected outages during critical fire-fighting operations.
High reliability - With a robust mechanical/electronic dual interlock system, this device effectively prevents short circuits by avoiding parallel connections of two power sources.
Fast response - Ensures a rapid transition with a swift switching time ≤ 1 second, catering to critical loads that demand an even quicker response of ≤ 0.2 seconds.
Fire signal linkage - Receives fire control center signals and securely locks the backup power supply, ensuring an unwavering operation during emergencies.
Switch structure explained:
1. Electric key lock:This feature controls the internal power supply of the switch. When the electric lock is unlocked, the switch can be operated automatically and remotely. Conversely, when locked, operation is restricted to manual handling only.
2. Operating handle:The switch can only be operated manually with the handle when the electric lock is secured, ensuring controlled access and operation.
3. Mechanical padlock:During inspections, place the switch in the '0' position using the operating handle, engage the padlock mechanism, and secure the padlock. This effectively disconnects the internal power supply, rendering the switch inoperative both electrically and manually, facilitating safe inspections.
4. Position indication:Indicates the operational status of the switch (I, 0, II), providing clear visibility into its current state.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Ensure your Intelligent Control ATS Automatic Transfer Switch is installed in a dry, well-ventilated area. It should be strategically placed near the main and backup power supply inlets for hassle-free operation and swift maintenance.
Wiring specifications: Connect the main and backup power supplies meticulously to the ATS input terminals, ensuring the output terminals are linked to the load. Carefully distinguish the phase sequence (L1/L2/L3/N/PE) for optimal performance and security.
Switching test: Upon powering on, simulate a main power failure to validate the swift automatic switching time (typically ≤ 1.5s), ensuring the load remains continuously powered with no interruption.
Safety requirements: Ensure reliable grounding and that the shell's protection level is suitable for its environment, such as IP40 for indoor use. Adherence to the GB/T 14048.11 standard is mandatory for safety and performance assurance.
