Automatic Transfer Switch (ATS) is an innovative electrical device designed to seamlessly transition between two power sources (main/backup), guaranteeing uninterrupted power flow to essential operations and preventing costly disruptions, data misplacement, or equipment impairment due to power interruptions.
- Core Functions
Automatic Switching - When the primary power source experiences issues such as power loss, undervoltage, or overvoltage, it intuitively switches to the alternative power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Empowers you with manual overriding capabilities for straightforward maintenance or urgent situations.
Zero Second Switching (Optional Feature) - Certain models offer flawless transitions, ideal for environments demanding unparalleled power reliability, such as data centers and medical equipment.
Effortlessly fortify electrical safety, ensuring key sectors always stay powered!
Intelligent Monitoring: Continuous voltage and frequency surveillance, automatically initiating switching upon anomaly detection.
High Reliability: Crafted with industrial-grade precision, supports frequent usage, offering a durability of over 10,000 cycles.

Fire Alarm Function of ATS
In the critical fire power supply systems, our dual power automatic transfer switch (ATS) goes beyond the norm. Not only does it seamlessly transition between main and backup power sources, but it also features an advanced fire alarm linkage function. This ensures uninterrupted power to essential fire safety equipment-such as smoke exhaust fans, fire pumps, and emergency lighting-even during a blaze. It further provides real-time feedback to the fire control center, guaranteeing heightened responsiveness and safety.
Forced Switching - This robust feature ensures that, even when the main power supply returns, the backup power remains active until manually reset. This prevents accidental power outages during critical fire extinguishing operations.
High Reliability - Our mechanical/electronic dual interlock system guarantees utmost reliability, skillfully avoiding any short circuits that could be caused by the parallel connection of two power sources.
Fast Response - Lightning-fast switching time of ≤ 1 second ensures your critical loads are powered without delay, with some systems requiring switches as rapid as ≤ 0.2 seconds.
Fire Signal Linkage - Ingeniously receives signals from the fire control center, ensuring the backup power supply is forcibly locked, fortifying your safety measures.
Switch Structure Explanation:
1. Electric Key Lock:This essential feature controls the internal power supply of the switch. When the electric lock is open, the switch operates automatically and remotely. When closed, manual operation via the handle is required.
2. Operating Handle:To manually operate the switch using the handle, ensure the electric lock is securely closed.
3. Mechanical Padlock:During inspections, rotate the switch to the '0' position using the operation handle. Subsequently, pull the padlock mechanism and secure it with the padlock to proceed with inspections. Engaging the mechanism padlock will cut off the internal power supply, disabling both electrical and manual operations of the switch.
4. Position Indication:Indicates the working status of the switch with positions (I, 0, II), ensuring clear and precise monitoring.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Select a dry and well-ventilated area for installation, strategically positioned near both the main and backup power supply inlets. This ensures seamless access for operation and maintenance.
Wiring specifications: Ensure precision in connecting the main and backup power supplies to the ATS input terminals. The output terminal should be precisely linked to the load while strictly maintaining phase sequence integrity (L1/L2/L3/N/PE).
Switching test: Once powered on, simulate a main power outage. Verify the quick automatic switching time-typically within 1.5 seconds-to guarantee uninterrupted power supply to the load.
Safety requirements: Ensure the device is reliably grounded. The shell protection level must align with environmental specifications (e.g., IP40 for indoor settings) and must comply with the rigorous GB/T 14048.11 standard.
