The PSTX soft starters offer complete motor protection in one device and also work in the event of load or mains irregularities. Motor protection is ensured by PT-100, residual current, overvoltage and undervoltage protection and other functions. Various start, stop and torque setting options enable precise adjustments to the respective application. The pump cleaning can, for example, alternately reverse the pump flow and thus free the pump impeller of dirt. The slow forward and reverse inching operation increases flexibility, for example when operating conveyor belts and cranes. A built-in bypass guarantees energy efficiency by reducing heat development during operation. The display and menu navigation are user-friendly.
