Automatic Transfer Switch (ATS) This state-of-the-art electrical apparatus seamlessly manages the transition between two distinct power sources (primary and backup), ensuring a consistent power flow to essential systems, effectively preventing any halts in production, data losses, or equipment failures due to unforeseen power interruptions.
- Core Functions
Automatic Switching - In the event of a power supply failure, such as an outage, undervoltage, or overvoltage, the system swiftly transitions to the backup power source (like a generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual switching for streamlined maintenance or in urgent scenarios, ensuring operational efficiency.
Zero Second Switching (Optional) - Selected models provide flawless transitions crucial for high-demand environments requiring uninterrupted power, such as data centers and medical equipment.

Sophisticated Connecting Terminal (Prolonged Circuit Board Durability Test For an extensive 48 hours)
Advanced Fire Alarm Functionality of ATS
Within the realm of fire power supply networks, the dual power automatic transfer switch (ATS) is meticulously designed to achieve seamless automatic transition between the primary and backup power sources. It also boasts an innovative fire alarm linkage, ensuring an uninterrupted power supply to vital fire safety equipment such as smoke exhaust fans, fire pumps, and emergency lighting. This sophisticated system provides immediate status feedback to the fire control center in the event of a fire, ensuring security, reliability, and peace of mind.
Robust Forced Switching Mechanism - During fire situations, even if the primary power is restored, the system insists on utilizing backup power until a manual reset occurs. This crucial feature prevents any unexpected outages that could hinder firefighting efforts.
Exceptional Reliability - Equipped with a dual mechanical and electronic interlock system, this technology effectively prevents short circuits that could result from the simultaneous connection of dual power sources, providing unparalleled safety and reliability.
Instantaneous Response - Featuring a switching time of ≤ 1 second, and for some critical loads, an impressive ≤ 0.2 seconds, this ensures minimal disruption in power supply, maintaining continuous operation under critical circumstances.
Fire Signal Integration - The system skillfully receives and acts upon signals from the fire control center, ensuring the robust and unwavering security of the backup power supply.
Comprehensive Switch Structure Explanation:
1. Electric Key Lock:This feature controls the internal power supply lines of the switch. When the electric lock is disengaged, the switch allows for automated and remote operations. On the other hand, when the electric lock is engaged, manual operation via handle becomes possible, offering versatility and control.
2. Operating Handle:To operate the switch using the handle, ensure the electric lock is securely engaged, allowing for a seamless and controlled operation.
3. Mechanic Padlock:For inspection, first rotate the switch to the "0" position using the handle. Then, secure the padlock mechanism to disconnect the switch's internal power supply. This step prevents the switch from being in electric mode or manually operated, ensuring a safe inspection environment.
4. Position Indication:Displays the operational status of the switch (I, 0, II) with utmost clarity and precision, allowing for immediate understanding and decision-making.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location:Select an installation site that is both dry and well-ventilated, ensuring it is conveniently near the main and backup power supply inlets. This deliberate positioning supports seamless functionality and facilitates efficient maintenance with minimal disruption.
Wiring specifications: Carefully connect both the main and backup power supplies to the ATS input terminal. Ensure that the output terminal is firmly connected to the load. Pay close attention to accurately identify and arrange the phase sequence L1, L2, L3, N, and PE to guarantee peak performance and heightened safety standards.
Switching test: With the system powered, simulate a main power outage to test the effectiveness of the ATS. Confirm that the automatic switching time remains exceptionally rapid (typically ≤ 1.5 seconds), ensuring the load remains consistently operational and without interruption.
Safety requirements: Ensure the system is reliably grounded, with the shell's protective level tailored to suit the environmental conditions (for example, IP40 for indoor applications). Adherence to the GB/T 14048.11 standard is essential for maintaining both compliance and safety integrity.
