Product Description

Product Description

Scope of application
This series of AC motor solid state soft starter is a new type of motor starting equipment which is designed and produced by using power electronics technology, microprocessoi technology and modern control theory. The product can effectively limit the starting current of asynchronous motor when starting, using a unique protection algorithm can effectivel protect the motor and related equipment, is widely used in fans, pumps, conveying and compressors and other loads, is the traditional star/triangle conversion, autobuck, magnetic control buck and other buck starting equipment ideal replacement products.

 

Product characteristics

• Detect the load voltage and current to achieve double closed-loop control,and realize the smooth and vibration-free starting of each load;
• A variety of starting modes,better match, adaptto a variety of load starting;
• Structure optimization: the unique and compact modular structure is very convenient for user system integration;
• With a variety of protection functions: lack of phase, reverse sequence, overcurrent, load, three-phase current imbalance, high current, thermal overload, undervoltage, overvoltage, etc.,all aspects of the motor and related equipment protection;
• With a variety of control methods: keyboard, external control, communication, remote control (order declaration),etc. Floating ball,electric contact pressure gauge connection;
• It has the function of power grid shaking, and has stronger adaptability to the power grid with poor quality;
• Programmable digital input port D1,D2,can achieve reset,emergency stop,interlockingcontrol,start,stop,point and other functions;
• Programmable relay K2,K3 passive output can achieve starting, running, soft stop, fault, thyristo fault, current upper and lower limit feeding control output;
• 0~20mA/4~20mA analog output real-time transmission;
• Support Modbus RTU fieldbus function, easy networking;
• LCD can display and operation keyboard to achieve man-machine dialogue,real-time display of multiple motor,power grid data,support keyboard reference.

 

Product typical application

This series of soft starters is widely used in chemical industry, mining, construction, transmission and distribution equipment, hydropower and other industries.

• Fan -reduce the starting current, reduce and reduce the impact of the power grid;
• Water pump-Use the soft stop function to alleviate the water hammer effect of the pump and reduce the impact of the pipeline;
• Compressor -reduce the mechanical impact during the starting process, save the cost of mechanical maintenance;
• Belt conveyor -Smooth and gradual starting through a soft starter to avoid product displacement and material removal;
• Ball mill -reduce gear torque wear,reduce maintenance workload,reduce maintenance costs.

Conditions of use and installation

Use conditions have a great impact on the normal use and life of the soft starter, so please install the soft starter in a place that meets the following conditions of use.

• Power supply: mains, self-provided power station, diesel generator set;
• Three-phase AC: AC380V(-10%, +15%),50Hz;(Note: The voltage level is selected according to the rated voltage of the motor. For special voltage levels AC660V or AC1140V, please specify when ordering)
• Applicable motor: general squirrel cage asynchronous motor;
• Starting frequency: Standard products are recommended to start and stop no more than 6 times per hour;
• Cooling mode: Bypass type: natural air cooling; In line: forced air cooling;
• Installation mode: wall hanging
• Class of protection: lP00;
• Conditions of use: The external bypass soft starter should be equipped with a bypass contactor when it is used. In linear and built-in bypass type, no additional bypass contactor is required;
• Environmental condition: lf the altitude is less than 2000 meters, the capacity should be reduced. The ambient temperature is between -25°C~+40°C; The relative humidity does not exceed 90%(20°C±5°C),No condensation, no flammable, explosive, corrosive gas, no conductive dust; Indoor installation, good ventilation, vibration less than 0. 5G;
