Automatic Transfer Switch (ATS)
100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A
Automatic Transfer Switch (ATS) is an advanced electrical device engineered to seamlessly transition between two distinct power sources (main/backup), ensuring an uninterrupted power supply to essential loads and preventing disruptions, data loss, or damage to equipment due to unexpected power outages.
- Core Functions
Automatic Switching - In the event of a failure in the main power supply, such as a power outage, undervoltage, or overvoltage, the system promptly and automatically switches to a reliable backup power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Features support for manual override, allowing for straightforward maintenance or emergency procedures with ease.
Zero Second Switching (Optional) - Select models offer seamless transition capabilities, perfect for applications demanding unyielding power continuity, such as in data centers and medical equipment.

Advanced Fire Alarm Functionality of ATS
In the crucial fire power supply system, the Dual Power Automatic Transfer Switch (ATS) serves a vital role, not just by effortlessly switching between primary and backup power sources, but also by incorporating a sophisticated fire alarm linkage feature. This ensures that during a fire, essential fire equipment such as smoke exhaust fans, fire pumps, and emergency lighting continue to be powered seamlessly. It also provides real-time updates on operational status directly to the fire control center, thereby enhancing safety measures.
Mandatory Forced Switching - Even after the main power supply is restored, the backup power supply remains active until it is manually reset. This mechanism is crucial to prevent any accidental power outages during fire extinguishing operations.
Exceptional Reliability - Equipped with a mechanical/electronic dual interlock system, it effectively prevents the occurrence of short circuits that could arise from the parallel connection of two power sources.
Rapid Response Time - Ensures swift switching with a response time of ≤ 1 second, and for some critical loads, the response is as fast as ≤ 0.2 seconds.
Fire Signal Linkage Capability - Capable of receiving crucial signals from the fire control center, it forcibly locks the backup power supply to ensure uninterrupted power during emergencies.
Explanation of Switch Structure:
1. Electric Key Lock:This feature controls the internal power supply line of the switch. When the electric lock is open, the switch functions automatically and remotely. Conversely, when the electric lock is closed, the switch can only be operated manually using a handle.
2. Operating Handle:To operate the switch via the handle, it is mandatory to ensure that the electric lock is closed.
3. Mechanic Padlock:During inspections, firstly adjust the switch to the '0' position using the operating handle, then engage the padlock mechanism and secure it with the padlock. This action cuts off the internal power supply of the switch, rendering it inactive in electric mode and also inoperable manually, thereby ensuring a safe inspection environment.
4. Position Indication:This indicates the operational state of the switch (I, 0, II), ensuring clear visibility of its status.
Installation Instructions
Installation Method for the Dual Power Automatic Transfer Switch (ATS):
Installation Location: Ensure installation in an environment that is both dry and well-ventilated, positioning the unit where it is easily accessible to the main and backup power supply inlets. This strategic placement facilitates seamless operation and straightforward maintenance.
Wiring Specifications: Connect the main and backup power supplies directly to the ATS input terminal. The output terminal should then be connected to the load. It is crucial to strictly adhere to the phase sequence identification (L1/L2/L3/N/PE) to ensure optimal performance and safety.
Switching Test: Conduct a simulated test of a main power failure after the system is powered on. Confirm the automatic switching time, which should typically be ≤ 1.5 seconds, to ensure continuous power supply without any interruption to the load.
Safety Requirements: Ensure reliable grounding and that the enclosure protection level matches the environmental conditions (e.g., IP40 for indoor settings). Compliance with the GB/T 14048.11 standard is mandatory to meet rigorous safety and performance criteria.
