ABB Low Voltage Soft Starters

ABB Low Voltage Soft Starters

 The PSE softstarter range is the worlds first compact softstarters with Torque Control This makes the PSE range an excellent choice for pumping application where water hammering normally is a big problem With its compact design and advanced functionality the PSE is also a very efficient solution for other common applications such as compressors and fans

Torque control
The most important function when stopping pumps is torque control Since the PSE softstarter is optimized for controlling pumps this feature is a must

Builtin bypass for energy saving
Using bypass after reaching full voltage will greatly reduce the power loss and thereby save energy In the PSE softstarter range the bypass is builtin on all sizes which will give the most compact starting solution and reduce the need for wiring during installation

Coated circuit boards
All circuit boards in the new PSE softstarter have a protective coating to ensure a reliable operation even in tough environments like wastewater plants where corrosive gases and acids may exist

Motor protection
The PSE softstarter is equipped with builtin electronic overload protection protecting the motor from overheating Since no additional overload device is needed our efficient design saves both space installation time and ultimately money

Analog output
The analog output terminals can be connected to an analog current meter to show the current during operation and thereby eliminating the need for an additional current transformer The analog output signal can also be used as an analog input to a PLC

Display and keypad
The setup of the PSE softstarter is done using the four button keypad and the illuminated display providing a quick and easy setup While operating the display will also provide important status information such as current and voltage

External keypad
As an option the PSE softstarter can be equipped with an external keypad for easy setup and monitoring of the unit without opening the enclosure door The keypad can also be used to copy parameters between different soft starters
