The ATA QB-7 series motor soft starter is a new type of device that integrates power electronics technology and the latest motor control theories. It can be widely used in loads such as fans, water pumps, compressors, and ball mills, making it an ideal replacement for traditional starting devices like autotransformer reduced voltage starters, star-delta starters, and magnetic control reduced voltage starters.
ATA QB-H/S Series Medium Voltage Soft Starter
All application voltage levels
Wide application frequency
Wide range of applications
Suitable for all types of loads
The ATA QB-H series medium voltage soft starter device combines computer control technology with power electronics technology, using high voltage high power thyristors as the main switching components in the circuit. By changing the conduction angle of the thyristors, it controls the smooth rise and fall of the motor voltage and achieves contactless on-off, enabling smooth start and stop of the motor. It starts the motor with an ideal current, effectively reducing the impact on the power grid, lowering equipment vibration, noise, and starting mechanical stress, thereby extending the service life of the motor and related equipment.
GKGR Series General Mining Medium Voltage Soft Starter
Multiple security protection(up to 9)
Compatible with various installation environments
High protection level(for cabinet)：IP54
Flexible starting modes
The GKGR series mine general medium-voltage soft start control cabinet adopts DSP control technology. During startup, it detects current and power factor, controls output voltage, and reduces starting current to ensure smooth motor startup. Upon stopping, it controls output voltage and gradually decreases running current for a smooth motor stop. This effectively reduces the starting impact current of the motor, minimizes the impact on the power grid, and also reduces the mechanical impact force on the mechanical load devices connected to the motor, extending the equipment's lifespan and lowering the later operational and maintenance costs. The product also features protection functions against overload, three-phase imbalance, phase loss, undervoltage, starting overcurrent, and starting timeout faults. It is mainly suitable for the control and protection of starting, running, and stopping large power asynchronous or synchronous motors.
ATAF-H Series Medium Voltage Variable Frequency Soft Starter
Low power grid capacity requirements
High input power factor > 0.95
Fast response
High integration
The ATAF-H series medium voltage soft starter device is suitable for starting large and medium-sized medium voltage AC asynchronous motors and electrically excited synchronous machines. The soft starter device has characteristics such as low starting current, high starting torque, high input power factor, low demand on grid capacity, and smooth, impact-free starting. It has significant advantages that other voltage-reducing soft starter devices cannot match, especially in applications where the grid capacity is low and the starting current requirement is below the motor's rated current.
ATA QBLV10 Series Low Voltage Variable Frequency Drive
Current vector control
Wide speed range
Adaptive acceleration and deceleration
No impact speed tracking
The ATA QBLV10 series standard frequency inverter is a high-performance inverter that integrates vector frequency conversion technology, which can easily drive induction motors with its high-performance current vector technology. This product features a high-performance, high-quality, and high-power density design, significantly enhancing usability, maintainability, environmental friendliness, installation space, and design standards, further enhancing the user experience.
ATA QBMV Series Medium Voltage Variable Frequency Drive
Multi-core control platform improves overall performance
Wide voltage operating range
No pollution to the grid
Safe, stable and reliable
ATA QBMV medium voltage frequency converter is an IGBT type medium voltage frequency converter that integrates cutting-edge power electronics technology from around the world. It uses SPWM (Sinusoidal PWM) control technology to achieve variable frequency speed control of medium voltage motors. The aim is to enhance the performance of variable speed operation of medium voltage motors, improve the control level of medium voltage equipment, as well as the power factor and operating efficiency of the equipment, meet process control requirements, reduce motor energy consumption, and achieve energy saving and environmental protection.

In the extreme environment of deep-well mines, the stable operation of the drainage system is crucial. A large copper mine successfully applied six Changsha ATA GKGR-300/06(K) general-purpose high-voltage soft-start control cabinets to the main drainage system of its -660m section. This effectively overcame challenges such as extreme depth, high humidity, strong corrosion, high dust levels, and severe power grid fluctuations, ensuring the reliable operation of the drainage system.
