SIWOQ series ATS
SIWOQ series automatic and electric transfer switching equipment integrates switch and logic control. Thus, it's not necessary to use controller. The ATSE truly achieves mechanical and electrical integration. It has the functions of voltage detection, frequency detection, communication interface, fire feedback, electrical and mechanical interlocking, etc. which can realize automatic, electric remote, emergency manual control.
Operation is carried out through the logic control board which gives various logic commands to control the motor and gear-box. The motor drives the accelerating mechanism of spring stored energy and instantaneous release to quickly make and break circuit or changeover circuit. Realize safe isolation through visible conditions. All of which greatly increase the electrical and mechanical properties.
Entirety design of the switch below 100A is metal enclosure which is small and compact. Control part of the switch over 100A is metal enclosure and it adopts two control modes of automatic and electric. Switch part adopts DMC enclosure, which have high dielectric property, protective capability as well as operating safety.
The switch is used for automatic transfer between normal power supply and emergency power supply or automatic transfer and safety isolation of two load equipments.
The switch is beautiful, novel, simple, small size and has complete functions. It's the best choice among the similar products. SIWOQ series product has acquired China Compulsory Certificate.

1. Phase Angle Detection Technology
Balance in three-phase load is the foundation of safety in power supply. Unbalance in three-phase load ranges from decreasing power supply efficiency of line and distribution transformer to blowing the wire of one phase, burning out the switch and even single-phase of distribution transformer, etc caused by overloading in phase with heavy load.
SIWOQ series ATSE controller adopts phase angle detection technology, switch automatically transfers to emergency power supply (high quality power supply) when three-phase unbalance occurs in distribution line. Thus, it ensures safety use of distribution line and load equipment.
2. Self-detection Function
SIWOQ series automatic transfer switch has self-detection function which can make a detailed detection for power supply, voltage, phase, frequency, action. It is convenience for customer to test ATSE at regular intervals.
3. Fault Alarm
ATSE will give alarming for the normal (emergency) power supply failure to remind customer in order to avoiding accident caused by the problem of power supply quality when normal or emergency power supply occurs power failure, overvoltage, undervoltage, phase-lacking, phase abnormal, high frequency, etc in distribution line of ATSE.
4. Memory Storage Function
SIWOQ series automatic transfer switch has memory storage function, the fault information will be automatically recorded in memory chips after fault is detected by control system, and it is easy to inquire fault information and reason.
5. Control Part
Control part of SIWOQ series product is researched and developed by our company, it adopts power module of military goods quality, SMT manufacturing process which ensure the reliability of electronic material welding. All detected circuits of control system are heavy electric, light electric insulated in the use of photoelectric or magnetic electricity theory. Control device give a real-time monitoring to voltage, frequency and phase of two power supplies. It uses signal driving system for insulation current to control the mechanism. Compared with voltage signal driving, current signal driving has more anti-interference ability and the insulation technology improves the safety of the system. It is the first that passed EMC test set by GB14048.11 in China. The electric fast pulse achieves 5kV/5kHz which is better than the technical requirement 2Kv/5kHz in GB14048.11 standard.
