The PSTX softstarters provide complete motor protection in a single device and operate effectively even under 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 for precise customization to the specific application. For example, the pump cleaning function can alternately reverse the pump flow to free the pump impeller from contamination. The slow jog operation forward and backward increases flexibility, such as when operating conveyors and cranes. An integrated bypass ensures energy efficiency by reducing heat generation during operation. The display and menu navigation are user-friendly.
