Product description

These softstart and softstop devices are robust electronic control units for softstart and softstop of AC motors. By means of phase-angle control the current rises e. g drops continuously. The motor torque behaves in the same way during start-up e.g. deceleration. This ensures that the drive can start and stop without jerking. This eliminates the risk of damage to drive elements because the sudden starting e.g. deceleration 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.
