The PST(B) softstarter is the most advanced softstarter in
the ABB product portfolio and is equipped with almost all
imaginable features. This makes the PST(B) ideal for almost
every application.
Torque Control
The ABB torque control function is developed together with
pump manufacturers to ensure the best possible pump stop,
eliminating problems with water hammering and pressure
surges.
By-pass for energy saving
By-passing the softstarter after reaching full voltage, will save
energy and reduce the heat generaton. The PST softstarters
are equipped with extra terminals making the connection of an
external by-pass contactor easier and allowing all protections
to be active during by-pass. On the PSTB softstarters, an ABB
AF-contactor is already built-in, ensuring a compact starting
solution with minimal wiring during installation.
Advanced protections
The PST(B) softstarters are equipped with almost all protections
imaginable for protecting the motor, the softstarter and the
application. To offer more flexibility, all protections can be
tailored to your specific needs.
Flexible 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.
Fieldbus communication
Using the ABB FieldBusPlug, all the most common fieldbus
protocols are supported. Using the PLC system it is possible
to set-up the softstarter, read status information and also to
control the softstarter.
Display and keypad
The PST(B) softstarter is equipped with a full text display
showing all information in clear text in your own language.
To make it even easier to set-up, there are standard settings
for many common applications, such as centrifugal pump.
Selecting this will automatically provide all required settings
including torque control when stopping.
External keypad
As an option, the PST(B) 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.
