DOLD 0067032: UG9019.11/110/61 3AC200-480V 1-10S Softstarter with softstop

The softstart-softstop unit provides smooth starting and stopping of 3-phase asynchronous motors. 2 phases are controlled by power semiconductors in a way that the current can rise continuously. This provides also a continuous rising motor torque. This eliminates mechanical shock while starting. After successful starting the power semiconductors are bridged with internal relay contacts. This reduces internal power dissipation. The softstop function prolongs the stop time of the motor in order to avoid a sudden stop.
