Automatic Transfer Switch (ATS)
Available in various capacities to meet diverse needs: 100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A.
Automatic Transfer Switch (ATS) is a sophisticated electrical device engineered to seamlessly switch between two power sources (main and backup), thereby guaranteeing an uninterrupted power supply to crucial loads. This prevents production halts, data loss, and equipment damage due to power failures.
- Core functions that define unparalleled reliability and performance:
Automatic Switching - Instantly reacts when the primary power source experiences failure (such as outages, under-voltage, or over-voltage), seamlessly shifting to the backup power source (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual override for straightforward maintenance or emergency interventions.
Zero-second Switching (Optional) - Select models feature instantaneous switching, ideal for critical applications requiring uninterrupted power, such as data centers and medical equipment.
Effectively ensures electrical safety, keeping essential areas powered without fail!
Intelligent Monitoring: Continuously monitors voltage and frequency, automatically initiating switching when irregularities occur.
High Reliability: Features an industrial-grade design, supports frequent operations, and boasts a life expectancy exceeding 10,000 cycles.
Safety Protection: Equipped with overload and short-circuit protection, and an IP protection level that withstands extreme environments.

Fire Alarm Function of ATS
In the fire power supply system, the dual power Automatic Transfer Switch (ATS) is designed not only to ensure seamless automatic switching between main and backup power sources but also to incorporate a fire alarm linkage function. This essential feature ensures continuous power supply to critical fire equipment like smoke exhaust fans, fire pumps, and emergency lighting during a fire event, providing real-time status updates to the fire control center.
Forced Switching - Even upon restoration of the main power supply, the backup power supply remains active until a manual reset is performed. This prevents accidental power loss during firefighting operations.
High Reliability - Equipped with a mechanical/electronic dual interlock system to prevent short circuits due to parallel connections of two power sources.
Fast Response - Offers a rapid switching time of ≤ 1 second, with some critical loads requiring an impressive ≤ 0.2 seconds.
Fire Signal Linkage - Receives fire control center signals and forcibly maintains the backup power supply.
Switch Structure Explanation:
1. Electric Key Lock:Controls the internal power supply of the switch. When the electric lock is open, the switch can be operated automatically and remotely. If the electric lock is closed, operation is manual, using the handle.
2. Operating Handle:For switch operation via the handle, the electric lock must be securely closed.
3. Mechanic Padlock:During inspections, first set the switch to the '0' position using the operating handle. Pull the padlock mechanism and close the padlock to proceed: Activating the mechanism padlock cuts off the switch's internal power supply, disabling both electric and manual operations.
4. Position Indication:Indicates the working state of the switch (I, 0, II)
Installation Instructions
Installation Method for Dual Power Automatic Transfer Switch (ATS):
Optimal Installation Location: Position the ATS in a dry, well-ventilated area, strategically situated near both the main and backup power supply inlets. This ensures seamless operational efficiency and effortless maintenance access.
Wiring Specifications: Connect the main and backup power supplies to the ATS input terminal while ensuring the output terminal is linked to the load. It's crucial to meticulously adhere to the phase sequence (L1/L2/L3/N/PE) for optimal performance.
Switching Test Protocol: Conduct a simulated main power failure post-powering on. Confirm the automatic switching time is efficient (typically ≤ 1.5 seconds), ensuring continuous power supply to the load without interruptions.
Essential Safety Requirements: Ensure reliable grounding, with the enclosure's protection level tailored to match the environmental needs (e.g., IP40 for indoor settings), fully compliant with the GB/T 14048.11 standard.
