Deep cooperation and quality upgrade: We have reached a deep cooperation with Hubei Taiji, a domestic listed company, and adopted customized modules and thyristors, which are different from the common modules in the market. This significantly enhances the load capacity and lays a solid foundation for the efficient operation of the equipment.

Streamlined design, cost savings: No need to install external bypass contactors, effectively saving installation space, reducing cable costs, simplifying the installation process, and making installation more convenient and faster.

Innovative control, easy start: Compared with conventional soft starters, a new square torque start control method has been added, providing a greater starting torque, achieving easy and smooth start, and adapting to more complex working conditions.

Real-time monitoring, safety assurance: Equipped with a PT100 input terminal, it can monitor the motor temperature in real time, promptly grasp the motor's operating status, effectively prevent faults caused by abnormal temperature, and ensure the safe operation of the motor.

Humanized design, worry-free installation: It adopts plug-and-pull control terminal blocks, making installation and operation simple and convenient. Just unplug the terminal blocks to complete the wiring and then reinject them, which greatly improves the installation efficiency.

Simulation testing, reliable verification: It is equipped with operation simulation function. Even when the main circuit of the soft starter is not connected to the power supply voltage, it can simulate the starting, running and stopping process of the motor, quickly confirming whether the working state of the soft starter's own components is normal.

Emergency support and continuous operation: An emergency start function has been added. Even in the event of a sudden breakdown of one phase of the thyristor, the soft starter can still maintain normal operation, ensuring the continuous operation of key equipment and reducing the risk of shutdown.

Product Application

Products can be used in metallurgy and chemical industry, compressors, cranes, municipal engineering occasions.

Crusher, sort stones of different sizes.

Online soft starter is widely used in the crusher industry, it can be used in impact crusher, jaw crusher, cone crusher, hammer crusher and so on. Can be used on high-power host, reduce the starting current, reduce the mechanical impact. The soft starter can automatically adjust the output power of the motor according to the actual load of the crusher. When the crusher is in no-load or light-load operation, the soft starter reduces the voltage and current of the motor, so that the motor runs at a lower power, so as to achieve the purpose of energy saving. According to statistics, after using the soft starter, the energy consumption of the crusher can be reduced by about 10%-30%.

Air compressor

Air compressor soft starter is a special soft starter tailored for various air compressors. Installing a soft starter on the air compressor can make the air supply pressure stable, and through the pressure regulator, the air compressor can keep working under the set pressure value, the pressure is stable and reliable, and the pressure can be stepless setting and adjustable at any time. Motor to achieve soft start, compressor service life and maintenance cycle will be greatly extended. The air compressor exhaust volume is controlled by the air compressor speed, the air valve plate in the cylinder is no longer repeatedly opened and closed, and the working conditions such as the valve seat and spring are greatly improved, which avoids the sharp flow and impact of high temperature and high pressure gas, and reduces the maintenance workload.

High-definition LCD four-line display, easy to operate. It comes with multiple national language displays and can be customized when necessary. The keyboard is pluggable and easy to move.

The thyristor with an internal bypass soft starter only works during startup and switches to the contactor during operation, so it generates less heat. However, we still installed a fan to cool the contactor. Install a fan to cool it down. All 75KW and above 7000 series soft starters are equipped with 24V high-speed DC fans, providing 360° all-round heat dissipation and stronger wind force. It not only reduces unexpected shutdowns caused by overheating, but also significantly extends the service life of the soft starter.

We have deep cooperation with Hubei Taiji, a domestic listed company, and use customized modules and thyristors, different from the generic modules supplied on the market, to improve the load capacity. Our DC contactors are also specially customized, all featuring silver contacts. The contact surface of the contacts is larger and can achieve nearly 100,000 engagement times, significantly increasing the service life.

The main purpose of the soft starter circuit board brush paint (usually three anti-paint, insulating paint or moisture-proof coating) is to protect the stability and life of the circuit board in a complex working environment, in order to ensure the service life of the circuit board is longer, we all use high-quality patches and plug-ins, the probability of failure is very low, and all use the machine spray three anti-paint, moisture-proof, dustproof, anti-short circuit. Increased durability and safety.

The unique emergency operation function. Conventional soft starters cannot operate when one phase of the thyristor is damaged. The emergency operation function of the 7000 series enables the soft starter to still operate in an emergency when one phase of the thyristor is broken down, reducing the economic losses caused by machine damage and shutdown for users.
