8 Softstarters | 1SFC132005C0201, rev.F
PSR – The compact range
Description
The PSR range is the most compact of all the ABB softstarter
ranges, thereby making it possible to fit many devices into
the same enclosure. The system concept with Manual Motor
Starters provides a far more compact starting solution than for
example a star delta starter.
Flexible mounting
PSR softstarters from 3 to 45 A are possible to mount on a din
rail, ensuring quick and easy mounting. Naturally, all sizes can
be screw mounted.
Few settings
The set-up of the PSR is easily done and confirmed using the
three clearly marked potentiometers on the front.
Built-in by-pass for energy saving
The built-in by-pass on all sizes does not only save energy;
it will also ensure the most compact ABB softstarter design
and reduce the installation time. Thanks to the reduced heat
generation, the softstarter can be mounted inside high IP class
enclosures.
Suitable for stopping pumps
Even without using torque control, the PSR range is designed
to reduce water hammering and will allow a superior stop
compared to the direct stop resulting from a star delta starter
or a DOL starter. See the special designed stop ramp with step
down voltage below.
System concept with manual motor starters
All PSR softstarter sizes can easily be connected to the
corresponding manual motor starters from ABB, using the
special designed connection kits. This will both make the
mounting and the connection easier and will provide a very
compact starting solution containing short circuit and thermal
protection, isolation function and soft starter - everything that
you need.
Start = 1 ... 20 sec
Stop = 0 ... 20 sec - including the step down voltage.
Step down = 2% reduction for each second increased stop ramp
Stop ramp 10 sec -> Step down 80% (20% reduction)
U
ini
= 40 ... 70% results in End voltage = 30 ... 60%
