The PSTX softstarters provide complete motor protection in a single device and operate effectively even during load or network irregularities. Motor protection is ensured through PT-100, residual current, over- and undervoltage protection, and additional functions. Various start, stop, and torque adjustment options allow precise adaptations to the specific application. For example, the pump cleaning function can alternately reverse the pump flow, thereby cleaning the pump impeller of contamination. The slow jog operation forward and backward increases flexibility, such as when operating conveyors and cranes. A built-in bypass ensures energy efficiency by reducing heat generation during operation. The display and menu navigation are user-friendly.
