Automatic Transfer Switch (ATS) is an advanced electrical device meticulously designed to automatically alternate between two power sources (main/backup), ensuring an uninterrupted and reliable power supply to critical systems. This prevents production disruptions, critical data loss, and potential equipment damage that could arise from power outages.
- Core Functions
Automatic Switching - When the main power supply is disrupted (due to power outage, undervoltage, overvoltage, etc.), it seamlessly switches to the backup power supply (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Provides manual forced switching capabilities, facilitating straightforward maintenance or critical emergency operations.
Zero Second Switching (Optional) - Certain models are engineered for seamless zero-second switching, catering to environments necessitating ultra-high power continuity, such as data centers and medical equipment.

Robust Connecting Terminal (Ensuring Circuit Board Reliability with Aging Test for 48 intensive hours)
Comprehensive Fire Alarm Functionality of ATS
In the realm of fire power supply systems, our dual power automatic transfer switch (ATS) stands out by seamlessly achieving automatic transitions between primary and backup power sources. It features an innovative fire alarm linkage function that ensures uninterrupted power supply to vital fire equipment-such as smoke exhaust fans, fire pumps, and emergency lighting-during a fire event. Additionally, it delivers instantaneous status feedback to the fire control center, securing the highest level of safety and operational continuity.
Resilient Forced Switching - Even upon restoration of the primary power, the backup power is prudently maintained until a manual reset is executed. This mechanism prevents inadvertent power outages during crucial fire extinguishing operations, safeguarding your infrastructure.
Unmatched High Reliability - Equipped with a dual mechanical/electronic interlock system, our ATS effectively prevents short circuits caused by the parallel connection of dual power sources, ensuring unparalleled safety and reliability.
Ultra-Fast Response Time - The ATS boasts a swift switching time of ≤ 1 second, accommodating even the most critical load requirements which demand a response time of ≤ 0.2 seconds, therefore guaranteeing the efficient management of power transitions.
Integrated Fire Signal Linkage - Receives crucial signals from the fire control center and automatically enforces a lock on the backup power supply, ensuring your safety protocols are never compromised.
Comprehensive Switch Structure Explanation:
1. Secure Electric Key Lock:This feature dominates the control of the switch's inner power lines. When the electric lock is open, the switch is capable of both automatic and remote operation. Conversely, when the lock is secured, operations are confined to handle use only, ensuring security.
2. User-Friendly Operating Handle:To operate the switch via the handle, the electric lock must be in a closed state, providing a layer of safety and operational integrity.
3. Durable Mechanic Padlock:For inspection purposes, switch the mechanism to the "0" position using the operating handle, engage the padlock mechanism, and secure the padlock. This action halts the internal power supply, disabling both electric and manual operations, thereby facilitating safe inspection procedures.
4. Clear Position Indication:This indicator provides precise feedback on the switch's operational stance, displaying positions (I, 0, II) clearly for user convenience and safety assurance.
Installation Instructions
Installation method of dual power automatic transfer switch (ATS):
Installation location: Ensure the switch is installed in a dry, well-ventilated area close to both primary and backup power supply inlets. This strategic placement facilitates effortless operation and seamless maintenance, optimizing performance and accessibility.
Wiring specifications: Connect the primary and backup power supplies directly to the ATS input terminals. Securely attach the output terminals to the load while meticulously distinguishing the phase sequence (L1/L2/L3/N/PE) to prevent any operational issues and ensure optimal performance.
Switching test: Conduct a simulated power failure test on the primary power source post-activation. Confirm the automatic switching is executed with impeccable swiftness (typically ≤ 1.5 seconds), ensuring uninterrupted power supply to the load during the transition.
Safety requirements: Ensure the unit's grounding is reliable and the shell's protection level aligns with environmental standards (e.g., IP40 for indoor settings), adhering strictly to the GB/T 14048.11 standard for heightened safety and compliance.
