Motor soft starter is the use of power electronics technology, micro-processing technology and modern control theory and design and production of the new starting equipment with the current international advanced level. The product can effectively limit the AC induction motor starting current when starting, can be widely used in fans, pumps, conveying class and the compressor load, is the traditional star / delta conversion, auto blood pressure, such as lowering blood pressure magnetron pressure equipment ideal replacement.
Feature1. Start: Select the load characteristics of different starting models and parameter settings can be the greatest degree of starting the motor to achieve the best results; three starting modes: voltage ramp start - get the maximum output torque; limit starting - can effectively limit the starting current; point move - to achieve test debugging. 2. High performance: As a result of high-performance microprocessors and powerful software support function to simplify the control circuit. No need to adjust the parameters of the circuit. You can get consistent, accurate and fast execution speed; high-strength anti-interference function . 3. High reliability: motor soft starter all electrical components have to undergo rigorous screening, the control board will be subject to 72 hours of high temperature cycle test and vibration test, thus ensuring high reliability of manufactured products; The optimized structure: Connection to qualify under the unique modular architecture and motivated compact y user-friendly integrated, complete; 5. Multiple protection features: motor soft starter motor starting on a variety of protection features (such as overcurrent, overload, se loss, overheating, etc.), or set of integration can reduce costs, simplify the circuit. 6. Keyboard settings: easy and intuitive operation display the keyboard, according to different load on the start and stop, run, protection and other parameters set, modify. WorksMotor soft starter (soft starter) is a set of novel motor control motor soft start, soft stop, and a variety of energy-saving light load protection functions in one, foreign called Soft Starter. Soft start opposite uses three parallel thyristors as regulator, between the power supply and the motor stator to access. This circuit such as a three-se full-controlled bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor is gradually increased, the motor accelerates gradually until full conduction thyristor motor working on the mechanical properties of the rated voltage, to achieve a smooth start to reduce the starting current, avoid starting overcurrent trip. Time until the motor reaches the rated rotation, start the process over, the soft starter has completed the task automatically replaced with thyristor bypass r for the normal operation of the motor rated voltage provided to reduce heat loss thyristors and prolong the life of the soft starter improve their work efficiency, but also make the grid to avoid harmonic pollution. Soft start stop function also provides a soft, soft start and soft stop opposite process, voltage decreases, the of rotations gradually decreased to zero, to avoid torque shock caused freewheel.
