ABB has released the new PSE softstarter family, a compact softstarter with two-phase torque control. . It is ideal for any application where space is limited but advanced functionality is required, the company said. 

The PSE features an efficient, compact design, and is suitable for all common applications including centrifugal pumps, fans, blowers, chillers, compressors and conveyor belts. Additional features include built-in class selectable electronic overload, built-in bypass and an LCD display.

A language neutral backlit display and a simple four-button keypad makes it easy to use. In addition, the built-in bypass reduces the number of connections, making it easy to mount and decreases both the time and cost of installation.

All circuit boards have a protective coating ensuring a reliable operation for environments like wastewater plants where corrosive gases and acids may exist. Torque control reduces fluid surges during the starting and stopping of centrifugal pumps. A patented two-phase torque control ensures balanced control of all three phases and eliminates the DC component during the starting and stopping of the motor, the company points out. The sophisticated control algorithm continuously monitors and generates commands which control motor torque to reduce the possibility of water hammering by smoothly accelerating and decelerating the motor.
