Automatic Transfer Switch (ATS)
100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A
Automatic Transfer Switch (ATS) is an indispensable electrical device engineered to facilitate seamless transitions between two power sources (main/backup), ensuring a consistent and uninterrupted power supply to vital loads. This safeguard prevents costly production interruptions, data loss, or equipment failure that can occur during power outages.
- Core Functions
Automatic Switching - In the event of main power supply disruptions, such as outages, undervoltage, or overvoltage, it instinctively shifts to the backup power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Designed to support manual forced switching, facilitating easy maintenance or urgent operations.
Zero Second Switching (Optional) - Select models provide seamless switching, ideal for environments demanding exceptional power continuity, such as data centers and medical equipment.

Advanced Fire Alarm Function of ATS
In the vital fire power supply system, our dual power automatic transfer switch (ATS) is engineered not just for seamless switching between primary and backup power sources but is also equipped with an essential fire alarm linkage function. This ensures the uninterrupted operation of critical fire safety equipment such as smoke exhaust fans, fire pumps, and emergency lighting during fire incidents. It provides instantaneous status feedback to the fire control center, safeguarding against any disruptions.
Forced Switching Mechanism - Remarkably, even with the restoration of the main power supply, the system continues to rely on the backup power until a manual reset is performed. This prevents unintended power outages during critical fire extinguishing operations.
Unmatched High Reliability - Featuring a robust mechanical/electronic dual interlock system, it expertly mitigates the risk of short circuits due to improper parallel connections of power sources.
Rapid and Efficient Response - With a swift switching time of ≤ 1 second, and even more impressive ≤ 0.2 seconds for critical loads, this system ensures minimal disruption.
Fire Signal Linkage System - Receives and processes signals directly from the fire control center, securely locking the backup power supply to ensure safety and reliability.
Comprehensive Switch Structure Explanation:
1. Electric Key Lock:This feature controls the internal power supply of the switch. When opened, the switch can be operated automatically and remotely. When closed, operations are restricted to manual handling only, enhancing security.
2. Operating Handle:To manually operate the switch using the handle, the electric key lock must first be secured. This safety step ensures controlled operations.
3. Mechanic Padlock:During inspections, first turn the switch to the '0' position using the handle, then engage the padlock mechanism, securely close the padlock to proceed. This action cuts off the internal controlling power, preventing both electric and manual operation, thus facilitating safe inspection.
4. Position Indication:Indicates the switch's operational status (I, 0, II), providing clear visibility and understanding of its current state.
Installation Instructions
Immerse yourself in the seamless installation process of the dual power Automatic Transfer Switch (ATS):
Installation Location: Select a dry, well-ventilated area strategically positioned near both the primary and backup power supply inlets, ensuring effortless operation and maintenance access.
Wiring Specifications: Connect the primary and auxiliary power supplies to the ATS input terminal. Ensure precision by connecting the output terminal to the load while strictly maintaining phase sequence integrity (L1/L2/L3/N/PE).
Switching Test: Conduct a simulated test by inducing a main power failure post power activation. Validate the automatic switching efficiency (typically ≤ 1.5 seconds) and confirm uninterrupted load power supply.
Safety Requirements: Ensure robust grounding coupled with a protective shell that aligns with environmental demands (such as IP40 for indoor settings), all in strict compliance with the GB/T 14048.11 standard.
