A-B 150-B97NBDB soft starter

The A-B 150-B97NBDB soft starter has the following characteristics, functions and application industries: ### Characteristics - **Smooth Start**: By controlling the changes in the voltage and current of the motor, it realizes a smooth accelerated start of the motor, avoiding vibrations and damages caused by excessive instantaneous current during the starting process, and effectively reducing the mechanical impact on the motor and the load. - **Reduction of Starting Current**: It can limit the instantaneous jump of the current and reduce the starting current to below three to five times the rated current, thus prolonging the service life of the motor. Meanwhile, it also alleviates the impact on the power grid, reduces the fluctuation of the power grid voltage, and protects the normal operation of other electrical equipment. - **Noise Reduction during Starting**: This soft starter can gradually accelerate the start of the motor, effectively control the rotational speed and acceleration of the motor, and further reduce the noise during starting, improving the working environment. - **High Reliability**: It adopts high-performance microprocessors to digitally process the signals in the control system, avoiding excessive adjustments of the previous analog circuits, thus obtaining excellent accuracy and execution speed, and possessing relatively high reliability and stability, enabling it to operate stably for a long time.

- **Strong Anti-interference Ability**: The signals in the control unit are all isolated by photoelectric means, and different anti-noise levels are set, which can effectively avoid the malfunction of the soft starter caused by the interference on the main power grid, ensuring its normal operation in a complex electrical environment. - **Easy Maintenance**: It consists of 4 light-emitting diodes and 4 dial switches to form a monitoring signal coding system, which can monitor the working status of the system equipment 24 hours a day. Meanwhile, it provides rapid fault diagnosis, facilitating users to discover and solve problems in a timely manner, reducing maintenance costs and downtime. - **Optimized Structure**: It adopts a unique compact structural design, which is especially convenient for users to integrate it into the existing systems, saving system modification costs for users. ### Functions - **Soft Start Function**: During the starting process, by controlling the conduction angle of the thyristor, the input voltage of the motor gradually increases from zero until it reaches the rated voltage, thus realizing the soft start of the motor and effectively reducing the current impact during starting. - **Soft Stop Function**: When the motor needs to stop, the soft starter will gradually reduce the input voltage of the motor, making the motor stop rotating in a stable state, avoiding the torque impact and mechanical damage caused by the sudden stop of the motor, and prolonging the service life of the motor and related equipment. - **Current Limiting Function**: It can limit the magnitude of the starting current according to the preset current limiting value, ensuring that the starting current is within the range that the power grid and the motor can withstand, and preventing various problems caused by excessive starting current. - **Multiple Protection Functions**: It has multiple protection functions such as overload protection, overcurrent protection, overheating protection, input/output phase loss protection, and thyristor short-circuit protection. When abnormal situations occur, it can quickly cut off the power supply or take corresponding protection measures to avoid damage to the motor and the soft starter, ensuring the safe and reliable operation of the equipment. - **Light Load Energy-saving Function**: When the motor load is light, the soft starter will reduce the operating voltage and current of the motor, reduce the power loss and heat generation of the motor, improve the operating efficiency and service life of the motor, and achieve the purpose of energy saving and consumption reduction. ### Application Industries - **Metallurgical Industry**: In the metallurgical production process, for equipment such as rolling mills, cranes, and blowers in steel plants, using the A-B 150-B97NBDB soft starter can achieve smooth start and stop, reduce the mechanical wear and electrical faults of the equipment, and improve production efficiency and equipment reliability. - **Petrochemical Industry**: This soft starter can be widely applied to various types of equipment such as pumps, compressors, and fans in the petrochemical field, effectively reducing the impact of the starting current on the power grid, protecting the equipment from damage caused by current impact, and ensuring the stable operation of the production process. - **Construction and Building Materials Industry**: For equipment such as tower cranes, concrete mixers, and elevators at construction sites, as well as crushers, ball mills, and belt conveyors in building materials production enterprises, using this soft starter can realize the soft start and soft stop of the equipment, prolong the service life of the equipment, and improve the safety of construction and production. - **Mechanical Manufacturing Industry**: For various machine tools such as lathes, milling machines, and drilling machines in mechanical manufacturing factories, as well as processing equipment such as punching machines and injection molding machines, by installing the A-B 150-B97NBDB soft starter, the current impact and mechanical vibration during starting can be reduced, the processing accuracy and equipment stability can be improved, and the equipment maintenance cost can be reduced. - **Water Treatment Industry**: For equipment such as pumps and blowers in water treatment plants, the soft starter can achieve smooth start and stop, avoid the pressure impact on the pipe network system, and at the same time reduce the operating noise of the equipment, improving the operating efficiency and stability of the water treatment system. - **Mining Industry**: For equipment such as crushers, conveyor belts, and ventilators in mining, using this soft starter can effectively reduce the starting current, reduce the impact on the power grid, protect the equipment to operate stably in a harsh working environment, and improve the safety and reliability of mining production.
