Compact Softstarter with Torque Control

Dec. 1, 2011
PSE softstarter is a family of compact softstarters with two-phase torque control.

Additional features include built-in class selectable electronic overload, built-in bypass and a LCD display. The compact design is suitable for common applications including centrifugal pumps, fans, blowers, chillers, compressors and conveyor belts. Units include a language neutral backlit display, simple four-button keypad and a built-in bypass that reduces the number of connections. All circuit boards have a protective coating for environments like wastewater plants where corrosive gases and acids may exist. 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 control algorithm continuously monitors and generates commands that control motor torque to reduce the possibility of water hammering. With the addition of the PSE, the softstarter portfolio now includes three distinct ranges.
