Welcome to G-TV! Today, we will be looking at ABB’s PSE Series Soft starters. The PSE
soft starter range is one of the first compact soft starters 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.
Some of the features include, Torque control, built in by-pass for energy saving, coated
circuit boards, motor protection, analog output, display and keypad, and external keypad. Torque
control - The most important function when stopping pumps is torque control. Since the
PSE soft starter is optimized for controlling pumps, this feature is a must. Built-in by-pass
for energy saving - Using the built-in by-pass after reaching full voltage will greatly reduce
the power loss and thereby save energy. In the PSE soft starter range, the bypass 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
PSE soft starter 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 soft starter is equipped with built-in electronic overload protection,
protecting the motor from overheating. Since no additional overload device is needed, the
design saves 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
soft starter is done by 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 soft starter
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
soft starters. ABB’s PSE Series Soft starters, along with thousands of other products and
