PSE – The efficient range

Description

The PSE softstarter range is the world’s first compact softstarter

range with torque control. This makes the PSE range an ideal

choice for pumping applications where water hammering

normally is a big problem. The compactness and advanced

functionality of the PSE means that it is also a very efficient

solution for other 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, preventing 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. This

eliminates the need of 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 softstarters.
