General situation of motor soft starter:

　　Intelligent digital motor soft starter adopts intelligentized digital control, takes single chip computer as the center, and SCR module as the actuator to control the motor fully. It is suitable for the control of squirrel cage asynchronous motor with various loads. It can start the motor smoothly under any working conditions, protect the drive system, reduce the impact of starting current on the power grid, and ensure the reliable start of the motor. Smooth deceleration soft parking function effectively solves the parking surge problem of inertial system and eliminates the anti-inertial impact of driving system, which is impossible to achieve by traditional equipment. Intelligent digital motor soft starter has complete system protection function, prolongs the service life of the system, reduces the cost of the system, improves the reliability of the system and is compatible with all kinds of functions of the starting equipment. It is the most ideal replacement product of traditional star triangle startup and auto decompression startup.

　　Main features of soft starter:

　　l  Computer simulation design.

　　l  SMT patch production process.

　　l  Excellent EMC performance, high temperature aging before leaving the factory, anti-vibration test.

　　l  Perfect system protection function, with voltage loss, under-voltage, over-voltage protection, full start-up overheating, start-up time too long protection.

　　l  Input phase-out, output phase-out, three-phase unbalanced protection.

　　l  Start up overcurrent, run overload, load short circuit protection.

　　l  Fault self-diagnosis (short circuit, overvoltage, undervoltage, single-phase grounding, motor overload, phase-breaking, blocking, plus intelligent program can be used to determine the working status of the drive system.

　　l  Modular combination design, according to the fault display content, quickly remove the fault.
