Automatic Transfer Switch (ATS) is a sophisticated electrical apparatus crafted to ensure an effortless and smooth transition between two independent power sources (main and backup), guaranteeing a continuous and reliable power supply to crucial systems. This prevents any disruptions in production, data loss, or equipment damage caused by unforeseen power interruptions.
- Core Functions
Automatic Switching - In the event of a failure in the primary power supply, such as a blackout or voltage aberrations, it promptly transitions to the backup power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual operation for enhanced maintenance flexibility or in urgent scenarios.
Zero Second Switching (Optional) - Certain advanced models offer uninterrupted transitions, which are critical for sectors that demand constant power, including data centers and medical equipment.

State-of-the-Art Advanced Fire Alarm Capabilities of the ATS
Within the intricate fire power supply network, the dual power automatic transfer switch (ATS) is meticulously engineered for a faultless, automatic transition between primary and backup power sources. This exceptional system features a state-of-the-art fire alarm linkage, ensuring an uninterrupted power supply to critical fire safety equipment such as smoke exhaust fans, fire pumps, and emergency lighting. Designed to perfection, this system provides immediate status feedback to the fire control center in the event of a fire, guaranteeing both security and reliability.
Impressively Robust Forced Switching Mechanism - In the event of a fire, even with the restoration of main power, the system requires the continued use of backup power until a manual reset is performed. This crucial feature is designed to prevent unexpected outages during critical firefighting operations.
Unparalleled and Exceptional Reliability - Incorporating a dual mechanical and electronic interlock system, this innovative technology prevents short circuits that could potentially arise from the simultaneous connection of dual power sources.
Lightning-Fast Instantaneous Response - Featuring an impressive switching time of ≤ 1 second, and for specific critical loads, an outstanding ≤ 0.2 seconds, ensuring that power supply disruption is minimized to an absolute minimum.
Seamless Fire Signal Integration - The system adeptly receives and efficiently acts upon signals from the fire control center, securely ensuring the backup power supply is maintained.
Comprehensive and Thorough Explanation of the Switch Structure:
1. Electric Key Lock:This component controls the internal power supply lines of the switch. When the electric lock is disengaged, the switch is capable of automated and remote operations. Conversely, when the electric lock is engaged, manual operation via the handle is enabled, providing flexibility and security.
2. Operating Handle:To operate the switch using the handle, it is essential to ensure that the electric lock is securely engaged, facilitating precise and reliable manual operation.
3. Mechanic Padlock:For thorough inspection, initially rotate the switch to the "0" position using the handle. Then, securely fasten the padlock mechanism to disconnect the switch's internal power supply. This prudent measure prevents the switch from being in electric mode or manually operated, ensuring a safe and comprehensive inspection.
4. Position Indication:Displays the operational status of the switch (I, 0, II) with unmatched clarity and precision, ensuring users are always informed.
Installation Instructions
Installation Method for the Dual Power Automatic Transfer Switch (ATS):
Installation Location:Select a dry, well-ventilated area to install the system, ensuring it's conveniently close to both the primary and backup power sources. This strategic positioning is vital for maintaining smooth operation and simplifying future maintenance efforts.
Wiring Specifications: Directly connect both the main and backup power supplies to the ATS input terminals. Ensure the output terminal is securely attached to the load. Carefully distinguish the precise phase sequence of L1, L2, L3, N, and PE to maximize performance and safety.
Switching Test: After energizing the system, simulate a main power outage to test its resilience. Confirm that the automatic switching occurs swiftly (typically ≤ 1.5 seconds), ensuring the load remains uninterrupted and operational.
Safety Requirements: Maintain robust grounding for the system, and adjust the shell's protection level according to environmental conditions (e.g., IP40 for indoor environments). Strict compliance with the GB/T 14048.11 standard is required for ensuring safety and adherence to regulations.
