Smart Soft Starter
There are six starting modes:Current limiting start, voltage ramp start, kick + current limit start, kick + voltage ramp start, current ramp start, double closed loop start. Parking mode:Soft parking, free parking. With a variety of protection functions:Over current protection, phase loss protection, three-phase current imbalance protection, overheat protection, motor overload protection, overvoltage protection, load short circuit protection. With dynamic fault recording function, it can record ten faults that have occurred recently, so that it is easy to find the cause of the fault. Soft start and soft stop time adjustable from 2 to 60 seconds. Large-screen LCD Chinese display, parameter setting, convenient query;Real-time display of working status, can replace some instruments and digital display functions. Realized double closed-loop control of current and voltage, closed-loop torque control, suitable for starting and stopping control of various motors. With programmable fault relay output, multi-function programmable relay output, 0-20mA (or 4-20mA) analog current output. When the motor does not need speed regulation, it can partially replace the inverter, and the cost is lower. Communication function:It can provide Chinese host computer software, which is convenient for users to debug and control remotely.
Complete motor protection
External fault input protection (instantaneous stop terminal):Used for external protection devices such as thermal relays. Loss of voltage protection:After the soft starter is powered off and after the call is made, no matter what position the control terminal is, it will not start by itself, so as to avoid injury accident. Long starting time protection:The soft starter will protect itself because the soft starter parameter setting is improper or other reasons cause the starting time to be unsuccessful. Soft starter overheat protection:Protection action when the temperature rises to 80 °C ± 5 °C, the action time is <0.1 seconds;When the temperature drops to 55 °C (lowest), the overheat protection is released. Input phase loss protection lag time:<3 seconds Output phase loss protection lag time:<3 seconds Three-phase unbalance protection lag time:<3 seconds, current deviation is greater than 50%. Starting overload protection time:The protection time when the current continues to be greater than 5 times the rated working current of the motor. Operation overload protection time:Reverse temperature protection is based on the rated working current of the motor.Refer to the trip protection time curve. Power supply voltage is too low.Protection lag time:When the power supply voltage is lower than the limit value of 50%, the protection action time is <0.5 seconds;Otherwise, the protection action time is less than 3 seconds when the set value is lower than the set value. Power supply voltage is too high.Protection lag time:When the power supply voltage is higher than the limit value of 130%, the protection action time is <0.5 seconds;Otherwise, the protection action time is <3 seconds when it is higher than the set value. Load short circuit protection lag time:<0.1 seconds, the current is 10 times of the nominal motor current rating of the soft starter.
SCKR series soft starter adopts MCU as the core and adopts intelligent digital control.It is suitable for the start of squirrel-cage asynchronous motor with various loads.It can make the motor start smoothly under any working condition, and it is very good for protection and dragging.The system reduces the impact of the starting current on the grid and ensures the reliable starting of the motor;Smooth deceleration and stopping can eliminate the anti-inertial impact of the dragging system;Complete system protection function, prolong the service life of the system, reduce the system cost and improve the reliability of the system.It is compatible with all the functions of all starting equipments.It is the most ideal replacement product for traditional star triangle, auto-coupled step-down starting, and magnetic control step-down starting.
