ABB PSTX370-600-70 Soft Starter - Advanced Motor Control & Energy Efficiency, 370 A, 208-600 V AC, IP66 Display, Modbus RTU Communication

The ABB PSTX370-600-70 Soft Starter is engineered for optimal motor control and energy efficiency. With a maximum operational current of 370 A and an operating voltage range of 208 to 600 V AC, this soft starter is versatile and robust. It supports a control voltage between 100 to 250 V AC at 50/60 Hz, making it adaptable to various power systems. The PSTX features a three-phase control for smooth soft start and stop, utilizing either a voltage or torque ramp. Its built-in bypass simplifies installation and enhances energy savings. Equipped with advanced functionalities, the PSTX offers current limit, kickstart, analog output, end-of-life (EOL) monitoring, motor heating, and pump cleaning. Additional features include jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump mode. The detachable full graphic display, rated IP66 and 4x for outdoor use, ensures user-friendly interaction. Communication with the PSTX is flexible, with options including hardwire inputs for Start/Stop/Reset, three programmable digital inputs, and built-in Fieldbus communication via Modbus RTU. Optional ANYBUS modules support major protocols like Profinet, Profibus, Modbus TCP, and Ethernet IP. An external adaptor and Fieldbus plug offer further connectivity options. Ideal for medium to large-sized three-phase motors, the PSTX is suitable for nominal currents from 30 to 1250 A in inline connection or 52 to 2160 A in inside delta connection. It is perfect for applications such as pumps, fans, compressors, and conveyors, providing a comprehensive solution for any motor starting needs.
