SL 9017

These soft starters are robust electronic control units for soft starting of AC motors. By means of phase-angle control the current rises continuously. The motor torque behaves in the same way during start-up. This ensures that the drive can start without jerking. This eliminates the risk of damage to drive elements because the sudden starting torque does not occur during direct switch-on. This feature allows a low-cost design of the drive elements. A significant reduction in starting noise can also be observed. In belt conveyor systems, slippage or tipping over of the conveyed material is avoided. After successful start-up, the power electronics are bridged by means of an internal relay contact in order to minimise the losses in the device.
