Description

The PSTX570-600-70 softstarter is a versatile and intelligent motor control solution designed for medium to large-scale industrial systems. It delivers smooth acceleration and deceleration through a fully adjustable three-phase voltage or torque ramp, reducing mechanical stress and power surges during startup. With a rated operational current of 570 A and voltage range of 208–600 V AC, it provides superior performance and reliability for demanding applications.

The soft starter features a built-in bypass for energy efficiency, advanced protection functions such as EOL, current limiting, and pump cleaning, along with motor heating and diagnostic capabilities. Its detachable IP66 graphic display allows intuitive configuration and real-time monitoring. PSTX communication flexibility includes Modbus RTU and optional ANYBUS modules for Profinet, Profibus, Modbus TCP, and Ethernet/IP protocols. For seamless integration and maximum performance, pair it with our industrial panel fabrication solutions.
