    Introduction 1.1.2 Operating Mode of the SIRIUS 3RW44 Electronic Soft Starter The 3RW44 soft starter has two antiparallel thyristors in each of the phases. There is one thyristor for the positive and one thyristor for the negative half wave. Using phase angle control, the r.m.s. value of the motor voltage is increased from a definable start voltage or start torque to the motor rated voltage within a selectable starting time using various control methods.
