ABB PSTX soft starters

Control Logic has introduced a range of soft starters from ABB adding updated functionality such as inline and inside delta connection and support for most major communication protocols.

Like direct online and star-delta starters, soft starters are used to start and stop motors in full-speed applications. The PSTX range combines many years of research and product development and eliminates problems associated with motor starting and stopping including electrical surges, spikes and high inrush currents.

There are three types of current limit on offer including standard, dual and ramp to provide full control of the motor during start-up. With advanced features normally associated with a VSD, the range includes torque control, slow speed forward and backward jog along with automatic pump cleaning and limp mode for continued operation in the event of a loss of one SCR.

The PSTX is available in various sizes with rated operational currents of 30 to 1250 A.
