The DS7 soft starter, a fully integrated component of the xStart system, is ideal for pump, fan and small conveyor belt applications. The DS7 replaces star-delta combinations and enables smooth starting of motors, for example in transport and material handling systems. In addition, smooth starting reduces the mechanical load on the entire system. With its extended service intervals and reduced operating costs, the DS7 soft starter stands out across the board.

During the start-up phase, the soft starter controls the power supply to the three-phase motor. The resulting soft start makes it possible to meet customer demands for jolt-free torque increases and targeted current reduction during the start-up phase. This is made possible by an ignition control system developed and patented by Eaton. This avoids DC components that would normally lead to uneven start-up, which in turn allows for smooth motor acceleration. This improves the overall operational performance, so that jolting in transport equipment, tooth flank impacts in gear mechanisms or pressure surges in piping systems are now a thing of the past.
