ZFeng MQ Series Dual Power Automatic Transfer Switch

MQ5 Automatic Transfer Switch (ATSE) is an automatic transfer switch that integrates switch and logic control without the need for an external controller, truly realizing mechatronics integration. It has functions such as voltage detection, frequency detection, communication interface electrical, mechanical interlocking, etc. It can achieve automatic, electric remote, and emergency manual control.

The operation is managed by the logic control board using various logic commands to operate the motor and gearbox. The motor is equipped with a switch spring to store energy, an instantaneous release acceleration mechanism, and a quick connection and disconnection circuit breaker or circuit conversion. Safety isolation is achieved through obvious visible states, greatly improving various electrical and mechanical performance.

Compliant with standards: IEC60947-6-1,GB/T14048.11

Technical Features

1. Fast Switching
   • Switching time typically ranges from tens of milliseconds to several seconds, depending on the load type and switch model.
   • For sensitive loads (e.g., IT equipment), switching time must be less than 10ms, requiring a static transfer switch (STS).
2. Intelligent Control
   • Equipped with a microprocessor-based controller for real-time power source monitoring and support for multiple switching modes (e.g., auto-transfer with auto-reversion, auto-transfer without reversion, mutual backup).
   • Parameters such as switching delay, voltage/frequency thresholds, and others can be configured.
3. High Reliability
   • Utilizes mechanical and electrical interlocking to prevent simultaneous connection of both power sources.
   • Provides protection against overload, overvoltage, undervoltage, phase failure, frequency anomalies, and other faults.
4. Remote Monitoring
   • Supports communication interfaces such as RS485, Modbus, and Ethernet, enabling integration with building automation systems (BAS) or power monitoring systems (SCADA) for remote monitoring and management.

Application Scenarios

1. Medical Facilities
   • Critical areas such as operating rooms, ICUs, and emergency departments require uninterrupted power to ensure the operation of medical equipment.
2. Data Centers
   • Servers, storage devices, and other IT equipment demand high power supply reliability to prevent data loss and business interruptions.
3. Industrial Production
   • Industries such as chemicals, metallurgy, and pharmaceuticals require continuous production lines to avoid accidents caused by power outages.
4. Commercial Buildings
   • Elevators, fire protection systems, and security monitoring require continuous power to ensure personnel safety and property protection.
5. Transportation Infrastructure
   • Airports, subways, and railways need to ensure the normal operation of signaling systems and communication equipment.
