The PSTX soft starters provide complete motor protection in a single device and operate effectively even in the presence of load or network irregularities. Motor protection is ensured through PT-100, residual current protection, overvoltage and undervoltage protection, as well as additional features. 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, thereby freeing the pump impeller from contamination. The slow forward and reverse jog operation increases flexibility, for instance, 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.
