ABB has released the new PSE softstarter family, the world’s first compact softstarter with two-phase torque control. Additional features include built-in class selectable electronic overload, built-in bypass and a LCD display. It is ideal for any application where space is limited but advanced functionality is required. Along with the existing ABB softstarter families it is now possible to find the ideal ABB softstarter for virtually any application and industry segment.

The PSE features an efficient, compact design, and is suitable for all common applications including centrifugal pumps, fans, blowers, chillers,compressors and conveyor belts.Easy to Set-up and UseThe market demands electrical devices that are easy to set-up and easy to use, and the PSE responds with a language neutral backlit display and a simple four button keypad. In addition,the built-in bypass reduces the number of connections, making it easy to mount and decreasing both the time and cost of installation. The PSE softstarter is designed to ensure exceptional reliability even in tough and harsh environments. 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. ABB’s 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 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. This makes the PSE softstarter an excellent choice for pumping applications where water hammering is a problem. The PSE has been designed to provide end-users with a softstarter with the most important features without adding unnecessary complexity. Referred to as “the efficient range”, the PSE will earn its moniker by providing unmatched value for the installed cost, and by the energy savings the built-in bypass will provide during its operational lifetime.
