Automatic Transfer Switch (ATS)
100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A
Automatic Transfer Switch (ATS) is an essential electrical device designed to automatically alternate between two distinct power sources (main/backup), thereby ensuring an uninterrupted supply of power to vital loads and preventing the disruptions, data losses, or costly equipment damages that power outages can cause.
-Core functions
Automatic Switching - When the main power supply experiences failure (such as outages, undervoltage, overvoltage, etc.), it seamlessly transitions to the backup power supply (such as a generator, UPS, or secondary mains power).
Manual priority mode - supports manual forced switching, facilitating maintenance or emergency operations with ease.
Zero second switching (optional) - Certain models offer seamless zero-delay switching, ideal for applications demanding utmost power consistency, such as data centers and medical equipment.
Efficiently safeguard your electrical systems and ensure that critical operations remain powered without interruption!
Intelligent monitoring: Continuous real-time detection of voltage and frequency fluctuations, automatically initiating switching upon detecting abnormalities.
High reliability: Built with an industrial-grade design, capable of supporting frequent operations, boasting a robust lifespan exceeding 10,000 cycles.
Safety protection: Features overload and short circuit protection, with an IP protection level that suits demanding and harsh environments.

Fire Alarm Function of ATS
In the sophisticated fire power supply system, the MTQ3-160 Automatic Transfer Switch (ATS) is ingeniously designed to seamlessly facilitate the automatic transition between primary and backup power sources. Beyond this, it is endowed with an essential fire alarm linkage function. This ensures that in a fire event, critical equipment like smoke exhaust fans, fire pumps, and emergency lighting continue to receive uninterrupted power supply. Moreover, the system is designed to provide immediate feedback on its operational status to the fire control center, enhancing safety and reliability in urgent situations.
Forced Switching - In scenarios where fire suppression is ongoing, even with the restoration of the main power supply, the MTQ3-160 ATS maintains the backup power until a manual reset is performed. This prevents unexpected power disruptions during critical firefighting operations.
High Reliability - The MTQ3-160 boasts a robust mechanical/electronic dual interlock system, meticulously designed to prevent short circuits caused by the simultaneous connection of two power sources.
Fast Response - With an impressive switching time of ≤ 1 second, and for certain crucial applications as quick as ≤ 0.2 seconds, the MTQ3-160 ATS ensures rapid transition to maintain power continuity.
Fire Signal Linkage - The MTQ3-160 ATS adeptly receives signals from the fire control center, diligently locking the backup power supply to secure uninterrupted power flow.
Switch Structure Explanation:
1. Electric Key Lock:This feature allows controlling the internal power supply line of the switch. When the electric lock is open, the switch is operable automatically and remotely. When closed, the switch must be operated manually using the handle.
2. Operating Handle:For manual operation using the handle, closing the electric lock is a prerequisite, ensuring secure handling.
3. Mechanic Padlock:Before inspection, shift the switch to the '0' position using the handle. Then, engage the padlock mechanism and secure it with the padlock, preparing it for inspection. Engaging the padlock mechanism disrupts the internal power supply, preventing both electric and manual operations of the switch.
4. Position Indication:This indicates the operational state of the switch, displaying positions I, 0, and II, ensuring a clear understanding of its current state.
Installation Instructions
Seamless Installation Method for Dual Power Automatic Transfer Switch (ATS):
Perfect Installation Location: Choose a dry and well-ventilated area that provides convenient access to both the primary and reserve power supply inlets. This strategic placement ensures effortless operation and maintenance.
Precise Wiring Specifications: Connect the primary and reserve power supplies meticulously to the ATS input terminal. Ensure the output terminal is linked to the load, maintaining a strict distinction in the phase sequence (L1/L2/L3/N/PE) for optimal performance.
Efficient Switching Test: Conduct a simulated main power failure once powered on, to verify the automatic switching time, which typically should not exceed 1.5 seconds. This guarantees uninterrupted power to the load.
Stringent Safety Requirements: Achieve reliable grounding with a shell protection level that corresponds to the environment, such as IP40 for indoor use. Ensure all installations comply with the GB/T 14048.11 standard for ultimate safety.
