JJR8000 series of intelligent motor soft starter is the use of power electronics skills, microprocessor skills and modern control theory skills to produce today's international first-class starting equipment, the product can constrain the starting voltage of the asynchronous motor when starting, can be used in fans, pumps, conveying and compressors and other heavy-duty equipment, is the star / triangle conversion, self-coupling step-down, magnetron step-down and other step-down equipment ambition replacement products.
Features:
Customized parameters can be selected directly by applying the load type through simple programming;
Three engine parameters are selectable, which is convenient for one motor soft starter to start different motor loads.
The motor reaction voltage is activated to complete the closed-loop control to ensure the successful start of the motor under various working conditions and different loads.
Three starting methods: the output torque that can be obtained by the voltage ramp starting method; Constrained starting current of constant current soft start method; The straight-start soft-start method can directly start the motor soft-starter.
Programmable delay start method, programmable chain control.
There is no phase sequence requirement for the input power supply.
The starting time and parking time can be digitally modified.
It has a variety of protection functions: overcurrent, three-phase current unbalance, overheating, phase loss, motor overload, etc.
The dynamic fault recall function makes it easy to find the cause of the failure.
The starting current and operating current can be found online.
The fieldbus's fully dynamic control monitoring starter is easy to network.
Chinese character flashing function: LCD LCD screen flashes various working parameters. Programming and fault states have text prompt instructions.
A brief introduction to the typical application of the product
Water Pump - Utilize the soft parking function to alleviate the water hammer flashing of the pump when stopped, saving the cost of system repair.
Ball mill - the use of voltage ramp starting, reduce the wear of gear torque, reduce the repair workload, both save time and save money.
Fan - Reduces belt wear and mechanical shock, saving repair costs.
Compressor - the use of current limiting, complete the smooth start, reduce the motor heat, and prolong the service life.
Belt conveyor - through soft start to complete the smooth and gradual starting process, to prevent product displacement and liquid spillage.

Advantages of frequency converters over soft start – Reynolds
(1) The starting torque is large and the power factor is high. Because the power factor of the motor is related to the working frequency, the power factor under the power frequency power supply is much lower than that under the low-frequency power supply when the motor is running at low speed. The inverter can control the motor from low frequencies and ...
