Description

The PSTX1050-600-70 soft starter is a high-performance motor control solution designed for smooth and efficient operation of large motors. With a rated operational current of 1050 A and voltage span of 208–600 V AC, it provides precise three-phase control through adjustable voltage or torque ramps. The unit integrates a built-in bypass for improved energy efficiency and reduced heat dissipation. PSTX also includes advanced motor protection features such as current limit, EOL, motor heating, and pump cleaning. For seamless system integration, it supports Fieldbus communication via Modbus RTU or optional ANYBUS modules, including Profinet, Profibus, Ethernet/IP, and Modbus TCP. When configuring large motor systems, enhance performance by integrating it into our industrial panel fabrication assemblies for optimized control and protection.
