The SIWOQ series of automatic and electric transfer switch appliances integrates switch and logic control, without the need for additional controllers, and can achieve electromechanical integration of automatic transfer switch appliances. It has functions such as voltage detection, frequency detection, communication interface, fire feedback, electrical and mechanical interlocking, and can achieve automatic, electric remote, and emergency manual control.
The operation is achieved by the logic control board managing the operation and operation of the motor and gearbox with various logic commands. The motor drives the acceleration mechanism of the switch spring energy storage and instantaneous release, quickly connecting and breaking circuits or conducting circuit transitions, achieving safe isolation through obvious visible states, greatly improving electrical and mechanical performance.
The overall design of switches below 100A is a metal shell, which is compact and sturdy. For switches above 100A, the control part is made of metal casing, using automatic and electric control modes. The switch part is made of unsaturated polyester glass fiber reinforced plastic casing, which has strong dielectric performance, protective ability, and reliable operational safety.
The switch is suitable for automatic conversion between commonly used and backup power sources in the power supply system, or for automatic conversion and safe isolation of two load devices. The switch design is beautiful, concise, and small in size.

Certification status
SIWOQ series automatic transfer switch appliances have passed self declaration and EAC certification
1. Phase Corner detection technology
Three phase load balancing is the foundation of safe power supply. Unbalanced three-phase loads may reduce the power supply efficiency of lines and distribution transformers, or overload of heavily loaded phases may lead to serious consequences such as burnout of phase conductors, switch burnout, or even single-phase burnout of distribution transformers.
The SIWOQ series automatic transfer switch controller uses the phase Corner detection technology internally. When serious three-phase imbalance occurs in the distribution line, and the absolute difference of phase voltage is greater than 120V, the switch will automatically switch to the standby power supply (high-quality power supply). This ensures the safe use of distribution lines and load equipment.
2. Self inspection function
The SIWOQ series automatic transfer switch has a self checking function, which can conduct detailed checks on power supply, voltage, phase, frequency, and action, making it convenient for customers to regularly inspect the automatic transfer switch.
3. Fault alarm
When there is an N-line error, power outage, overvoltage, undervoltage, phase loss, abnormal phase, or high frequency fault in the distribution line where SIWOQ is located, SIWOQ will display a fault code through LED for alarm, reminding users of faults in the common (backup) power supply and preventing accidents caused by power quality issues.
4. Memory storage function
The SIWOQ series automatic transfer switch has a storage and memory function. When the control system detects a fault situation, the information will be automatically recorded in the memory chip, making it easy to query the fault information and cause.
5. Control part
The SIWOQ series products adopt the SMT manufacturing process, ensuring the reliability of electronic material welding. The detection circuit of the control system adopts photoelectric or magnetoelectric principles for strong and weak current isolation. The controller monitors the voltage, frequency, and phase of both power sources in real-time. Using isolated current signals to drive the system control mechanism. Compared with voltage signal driving, current signal driving has strong anti-interference ability, and isolation technology improves the safety of the system. Passed the EMC test specified in GB14048.11 in China. The electrical fast pulse meets the technical requirements of 2kV/5kHz specified in GB14048.11 standard.
6. Internal arc extinguishing grid of the main body
The SIWOQ series automatic transfer switch is equipped with arc extinguishing grids in the main body, greatly improving the making and breaking capacity of ATSE.
7. Integrated dedicated pressure signal transmission template
The internal signal transmission of the SIWOQ series automatic transfer switch adopts an integrated dedicated pressure signal transmission template, which enhances the electrical insulation level of ATSE and improves the signal transmission anti-interference ability of the automatic transfer switch. At the same time, it also replaced the traditional microswitch as the era of transmitting signals. Ensuring the reliability of ATSE.
8. Transmission mechanism
The switch adopts a two gear transmission mechanism, and the gear material is modified nylon, which significantly improves the gear life and has the characteristics of sound absorption and noise reduction. Further improved the reliability of the ATSE transmission system.
9. Networking function
The SIWOQ series products adopt the SuperViewer software system, which can achieve networking
