PSE Open Softstarters

PSE Open Softstarter – The Efficient Range

The PSE has been designed to meet the most common requirements for machinery but is also specialized for pump operation(water segment). It combines the requested protections with a very compact design and built-in bypass. Remote operation with external keypad or over fieldbus is available as an option.

Features

Voltage ramp and torque control for both start and stop
Two-phase controlled
Current limit
Kick-start
Built-in bypass for energy saving and easy installation
Illuminated display that uses symbols to become language neutral
External keypad rated IP66 (Type 1, 4X,12) as an option
Analog output for display of motor current
Coated Circuit boards protecting from dust, moist and corrosive atmospheres
Built in overload features like Electronic overload, underload and locked rotor

Benefits

Secure motor reliability
The PSE includes the most important protections for handling different load situations that can happen to pumps e.g. overload and underload. The current limit gives you more control of the motor during start and allows you to start your motor in weaker networks.

Reduce installation time
On the PSE, the bypass is built in and verified by ABB, saving you time during installation and space in your panel. The keypad is language neutral and illuminated for easy set-up and operation in field. The compact design makes installation fast and easy

Increase productivity
Torque control is the most efficient way to stop a full speed pump. The PSE has a special torque stop ramp that is designed together with a pump manufacturer to eliminate water hammering in an optimal way.
