ABB softstarters – The complete range
ABB offers four different ranges of softstarters to cover
every customer need for solutions for motor sizes up to
1800 A. This page decribes the main characteristics of the
different softstarter ranges
PSR — The compact range
The PSR softstarter is the most compact of all the softstarter
ranges, thereby making it possible to design compact starting
equipments. The system concept with Manual Motor Starters
and the PSR provides a far more compact starting solution
than for instance a star delta starter.
Built-in by-pass reduces the energy loss and makes the
connection easier and with only three potentiometers, the
set-up couldn’t be any easier. Still, the optimized ramping
characteristics will ensure a very smooth start and stop for all
applications.
PSS — The flexible range
The PSS softstarter allows both in line and inside delta
connection making it a very flexible option. Just as on the
PSR softstarter, the few settings make the set-up very easy.
Connecting an external current transformer makes it possible
to activate the current limit function, which will allow you to
keep the current at a pre-set level also when starting heavy
duty applications. The PSS softstarter is the ideal solution
when looking for a robust solid state starting solution where
many starts per hour are required.
PSE — The efficient range
The PSE softstarter is the world’s first compact softstarter with
both built-in electronic overload for motor protection and torque
control for an excellent control of pumps. The compact design
with the most important functionality integrated provides a very
efficient starting solution.
The illuminated language neutral display and the four button
keypad make it easy to take advantage of all the advanced
functionality in the softstarter. The display will also provide all
the necessary information both during ramping and continuous
operation.
PST(B) — The advanced range
The PST(B) softstarter is the most advanced softstarter in the
range with almost all imaginable functionality included. All the
advanced protections for the motor, the softstarter and the
load ensure a trouble free operation. Pre-warnings even allow
problems to be detected before the motor needs to be stopped
and thereby avoiding unnecessary downtime.
The torque control function has been developed and tested
together with well known pump manufacturers to ensure
the absolutely best possible stop of pumps without water
hammering and pressure surges.
With the full text LCD display in your own language, pre-
programmed application settings and event logging, it couldn’t
be easier to set-up and operate.
By using the ABB FieldBusPlug, you can decide at any time
which bus protocol to use. The fieldbus system will allow you
to set-up, control and monitor the softstarter.
