ATA QB-H Series Medium Voltage Motor Solid State Soft Starter

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.

ATA QB-S Series Medium Voltage Motor Solid State Soft Starter

The ATA QB-S series medium voltage electric motor solid-state soft starter device achieves a perfect integration of the switch cabinet and soft starter. It is designed to match the most demanding industrial requirements with compact size, flexible input and output line configurations, a modular silicon box design, a brand new electronic PT sampling feedback system, and easy operation and maintenance.

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.
