WGQ1(AX1) Intelligent Dual Power Automatic Transfer Switch (ATS)

WGQ1(AX1) Intelligent Dual Power Automatic Transfer Switch (ATS)

Product Overview: The Ultimate Guardian of Uninterrupted Power

The WGQ1(AX1) Intelligent Dual Power Automatic Transfer Switch (ATS) is a high-performance, high-reliability electrical switching device engineered specifically for critical loads and environments where power supply continuity is non-negotiable. It represents the pinnacle of power transfer technology, seamlessly integrating advanced micro-processing control with robust switching mechanisms.

Designed to detect power anomalies such as interruptions, voltage sags, over/under voltage, and frequency variations, the WGQ1(AX1) automatically, rapidly, and seamlessly transfers the load between the Normal Power Source (N) and the Reserve Power Source (R). This capability is crucial for maximizing uptime, minimizing operational disruption, and safeguarding valuable assets in mission-critical applications.

The WGQ1(AX1) series offers a comprehensive range of solutions across various current ratings, making it the indispensable choice for data centers, hospitals, financial institutions, high-rise buildings, critical industrial facilities, and any application where power outage is simply not an option.

Core Features and Key Advantages

1. Extreme Reliability and High-Speed Automatic Transfer

The WGQ1(AX1) is built upon a foundation of speed and certainty:

• Sub-50ms High-Speed Transfer: Equipped with an embedded smart controller, the ATS initiates the transfer sequence immediately upon detecting a fault in the Normal Power Source. The typical contact conversion time is less than 50ms (or up to $\le 80ms$ for certain high-capacity models), ensuring that the impact of the outage on sensitive electronic equipment is minimized, effectively bridging the power gap.

• Dual Interlock Protection (Mechanical and Electrical): Safety is paramount. The device incorporates a redundant mechanical and electrical double interlock mechanism. This absolute protection prevents the simultaneous closure of the Normal and Reserve power sources—a critical feature that eliminates the risk of disastrous short circuits or parallel operation, guaranteeing system integrity and safety.

• Intelligent Monitoring and Fault Diagnosis: The system continuously monitors the key parameters of both power sources in real-time, including voltage (over/under), frequency, and phase sequence. Immediate and precise fault detection (e.g., loss of phase, undervoltage, overvoltage) triggers the automatic transfer procedure, maintaining load supply stability.

2. Smart Control, Flexibility, and Advanced Customization

The intelligent control unit provides unparalleled operational flexibility:

• Multi-Mode Operation: Offers essential operation modes to suit all scenarios:

  • Automatic (Auto) Mode: Full automatic detection, diagnosis, and transfer without human intervention.

  • Manual (Manual) Mode: Allows operators to manually initiate a transfer for maintenance, testing, or during specific emergency procedures.

  • Optional “Off” / “Zero Position” Mode: Specific models may offer a neutral position that simultaneously isolates the load from both power sources for enhanced safety during deep maintenance.

• Adjustable Transfer Delay and Restoration Delay (Intelligent Models): To prevent nuisance tripping and unnecessary switching caused by momentary grid fluctuations or transient dips during generator startup, the unit features adjustable delay settings (e.g., 0 to 60 seconds adjustable). Users can precisely tune the timing to match their specific load characteristics and grid stability conditions.

• Integrated Generator Control & Interlock: The intelligent models provide a dedicated generator start signal output interface. Upon failure of the Normal Source, the ATS sends an immediate start command to the standby generator set, achieving a fully automated, unattended power generation and transfer system.

3. Superior Performance and Robust Structural Design

The WGQ1(AX1) is engineered for endurance and high performance:

• PC Class or CB Class Availability: The series provides options tailored to specific short-circuit withstand and breaking requirements:

  • PC Class (Make and Withstand): Designed to safely close onto and withstand the thermal and dynamic effects of a short circuit.

  • CB Class (Circuit Breaker Type): Incorporates inherent overcurrent and short-circuit breaking capabilities, offering integrated protection.

• Compact, Modular Design: The streamlined, modular structure facilitates easy integration into existing power distribution cabinets or switchboards. Its reduced footprint simplifies installation and streamlines routine maintenance and inspection procedures.

• Extended Mechanical and Electrical Life: Utilizing premium contact materials and precision-engineered driving mechanisms, the ATS guarantees long-term durability. Specific models boast a mechanical life exceeding 5,000 operations and an electrical life exceeding 2,000 operations, ensuring sustained reliability over decades.

• Load Isolation (Zero Position Function): Models featuring the Zero Position function offer an immediate transfer to a state where both Normal and Reserve contacts are open, providing maximum isolation between the load and the power grid for heightened safety during critical operations or maintenance.

4. Comprehensive Safety and System Protection

Security and regulatory compliance are integral to the WGQ1(AX1) design:

• Integrated Protection Features: Depending on the model, the unit can incorporate built-in protection against short circuits, overloads, undervoltage, and phase loss, further enhancing the overall system robustness.

• EPS/Fire Linkage Interface: Intelligent models are equipped with a DC 12V-24V EPS (Emergency Power Supply) fire linkage interface. This feature ensures compliance with fire safety regulations, allowing the ATS to automatically isolate non-firefighting loads or mandate a transfer to the designated fire emergency power source upon receiving a fire signal.

• Clear Status Indication: A user-friendly control panel provides clear LED indicators for Normal Power status, Reserve Power status, and the current switching position, allowing personnel to monitor the operating status and quickly diagnose any issues at a glance.

• Remote Monitoring Capability: Certain intelligent models offer RS485 communication interfaces (Modbus protocol) for seamless integration into Supervisory Control and Data Acquisition (SCADA) systems, Building Management Systems (BMS), or remote monitoring platforms, enabling comprehensive remote management and data logging.
