SIKOSTART 3RW24 digital electronic motor controllers (SOFTDRIVE) are multifunctional electronic system to provide smooth acceleration, eceleration and a controlled level of starting current for use with three phase asynchronous motors. Apart from its basic functions, it also is equipped to protect the motor under various fault conditions.
With its advanced start & stop modes, extensive protections and improved fault diagnostics; the  controller has the maximum flexibility to suit any kind of load requirement. The SIKOSTART range of digital controllers utilize 6 thyristors, each phase has two thyristors in antiparallel configuration. By varying the thyristor conduction period, the voltage applied to the motor and hence the motor starting torque, are controlled. Two versions are available viz. Line connection (3-wire system) and Inside Delta connection (6-wire system).
