ABB PSTX37-600-70 Soft Starter: Advanced Motor Control & Energy Efficiency for 208-600V AC Systems

The ABB PSTX37-600-70 Soft Starter is engineered for optimal motor control and energy efficiency. Designed to handle a maximum operational current of 37 A, it operates within a voltage range of 208 to 600 V AC, with a control voltage between 100 to 250 V AC at 50/60 Hz. This advanced soft starter offers a three-phase control for smooth start and stop functions via voltage or torque ramp, and includes a built-in bypass for simplified installation and energy savings. Equipped with a variety of features, the PSTX37-600-70 includes current limit, kickstart, analog output, end-of-life (EOL) monitoring, motor heating, and pump cleaning functions. It also supports jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump modes as standard. The device is user-friendly, featuring a detachable full graphic display with IP66 and 4x outdoor rating for easy interaction. Communication with the PSTX is versatile, offering hardwire inputs for Start/Stop/Reset of faults, 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 provide additional communication options. The PSTX37-600-70 is ideal for medium to large-sized three-phase motors, supporting 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 application.
