Automatic Transfer Switch (ATS) This state-of-the-art electrical marvel automatically transitions between dual power sources (main/backup), ensuring an uninterrupted power supply to vital operations and preventing costly disruptions, data loss, or potential equipment damage associated with power outages.
- Core Functions
Automatic Switching - In the event of a main power supply failure, be it a blackout, undervoltage, or overvoltage, the system seamlessly transitions to a backup power source (such as a generator, uninterrupted power supply (UPS), or secondary mains power).
Manual Priority Mode - Facilitates manual switching to ensure effortless maintenance or swift emergency responses.
Zero Second Switching (Optional) - Select models offer seamless switching capabilities, ideal for environments demanding exceptional power continuity, such as data centers and critical medical equipment.

Cutting-Edge Fire Alarm Functionality in ATS
In our advanced fire power supply system, the dual power automatic transfer switch (ATS) excels by seamlessly switching between main and backup power sources. It is also equipped with a sophisticated fire alarm linkage function that guarantees uninterrupted power supply to essential fire equipment (like smoke exhaust fans, fire pumps, and emergency lighting) during a fire emergency. This feature ensures the system consistently provides real-time status updates to the fire control center for enhanced safety.
Comprehensive Forced Switching Capability - Even upon restoration of the main power supply, our system mandates that the backup power supply remains active until a manual reset is performed, safeguarding against unforeseen power outages during critical fire-fighting operations.
Unmatched High Reliability - Featuring a robust mechanical/electronic dual interlock system, our ATS prevents short circuits caused by the parallel connection of dual power sources, ensuring optimal safety and continuity.
Rapid and Efficient Response Time - Superior switching speed with a maximum of ≤ 1 second, catering to critical load requirements which demand an impressive ≤ 0.2 seconds.
Fire Signal Integration and Linkage - Capable of receiving signals from the fire control center, our ATS strategically locks the backup power supply to maintain system integrity.
Intricate Switch Structure Explanation:
1.Electric Key Lock Mechanism:The electric key lock controls the power supply within the switch. When unlocked, it allows for both automatic and remote operation. When locked, the switch is operable only via the manual handle, reinforcing security and control.
2.Manual Operating Handle:For manual operation of the switch, ensure the electric lock is secured in a closed position, allowing for safe and controlled handling.
3.Robust Mechanical Padlock System:For inspection purposes, initially rotate the switch to the "0" position using the operating handle. Following this, engage the padlock mechanism by closing the padlock, thus enabling the inspection process. Engaging the padlock mechanism effectively cuts off the internal controlling power supply, thereby preventing both electric and manual operations of the switch.
4.Position Indicator Clarity:This indicator clearly represents the operational status of the switch, displaying positions (I, 0, II) for easy understanding and monitoring.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Position the ATS in an area that is both dry and well-ventilated, strategically close to both the primary and secondary power supply inlets. This ensures seamless operation and simplifies maintenance.
Wiring specifications: Connect the primary and secondary power supplies to the ATS input terminals, while linking the output terminal to your load. Ensure strict adherence to phase sequence distinctions (L1/L2/L3/N/PE) for optimal functionality.
Switching test: Conduct a test by simulating a primary power outage post-activation. Confirm the automatic switching time is rapid (typically ≤ 1.5 seconds) and ascertain that the load remains uninterrupted.
Safety requirements: Ensure reliable grounding, match the enclosure's protection level to the environment (e.g., IP40 for indoor use), and strictly comply with the GB/T 14048.11 standard for safety and reliability.
