ABB PSTX105-600-70 Soft Starter - 105A, 208-600V AC, Advanced Motor Control with Built-in Bypass and Multi-Protocol Communication

The ABB PSTX105-600-70 Soft Starter is engineered for optimal motor control, offering a rated maximum operational current of 105 A and an operating voltage range of 208 to 600 V AC. Designed for versatility, it supports a control voltage between 100 to 250 V AC at 50/60 Hz. This advanced soft starter features a three-phase control for smooth soft start and stop, utilizing either a voltage or torque ramp. Its built-in bypass ensures easy installation and energy efficiency. The device provides RUN, TOR, and Event signals via relay outputs in a normally open state. Equipped with a range of functions, the PSTX includes current limit, kickstart, analog output, end-of-life (EOL) monitoring, motor heating, and pump cleaning. Additional features such as jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump mode are standard. The PSTX is user-friendly with a detachable full graphic display rated IP66 and 4x for outdoor use. Communication with the PSTX is flexible, offering four methods: hardwire inputs for Start/Stop/Reset of faults, three programmable digital inputs, built-in Fieldbus communication via Modbus RTU, and optional ANYBUS modules supporting major protocols like Profinet, Profibus, Modbus TCP, and Ethernet IP. An external adaptor and Fieldbus plug provide additional communication 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, making it a comprehensive solution for any motor starting needs.
