26 Softstarters | 1SFC132005C0201, rev.F
e
The PSE softstarter range is the world's 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.
Built-in by-pass for energy saving
Using by-pass after reaching full voltage will greatly reduce
the power loss and thereby save energy. In the PSE softstarter
range, the by-pass is built-in 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 built-in 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 set-up of the PSE softstarter is done using the four button
keypad and the illuminated display, providing a quick and easy
set-up. 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 set-up and monitoring of the unit
without opening the enclosure door. The keypad can also be
used to copy parameters between different softstarters.
