ABB (New Berlin, WI) has released the PSE soft starter family with two-phase torque control. Additional features include built-in class-selectable electronic overload, built-in bypass, and an LCD display. The PSE features a compact design, and is suitable for all common applications including centrifugal pumps, fans, blowers, chillers, compressors, and conveyor belts.
The soft starter offers a language-neutral backlit display and a fourbutton
keypad. All circuit boards have a protective coating for operation
in harsh environments. Torque control reduces fluid surges during
the starting and stopping of centrifugal pumps. A two-phase torque control
ensures balanced control of all three phases and eliminates the DC
component during the starting and stopping of the motor.
