Main functions of soft starter
Overload protection: the soft starter introduces a current control ring, which can track and detect the change of motor current at any time.The overload protection function is realized by increasing the setting of overload current and the reverse time limit control mode.
Missing phase protection function: when working, the soft starter detects the change of the three-phase line current at any time, and can make the missing phase protection response once the current breaks.
Overheat protection function: the temperature of the thyristor radiator is detected by the internal thermal relay of the soft starter. Once the temperature of the radiator exceeds the allowable value, the thyristor is automatically shut off and an alarm signal is sent.
Function of measuring circuit parameters: when the motor is working, the detector in the soft starter always monitors the running state of the motor and sends the monitored parameters to the CPU for processing, which analyzes, stores and displays the monitored parameters.Therefore, the motor soft starter also has the function of measuring circuit parameters.
Other functions: through the combination of electronic circuits, can also achieve other kinds of interlock protection in the system.
