PSR – The compact range
Description
Product description
• Wide rated operational voltage 208 – 600 V
• Rated control supply voltage 24 V DC or
100 – 240 V AC
• Rated operational current 3 – 105 A
• Wide ambient temperature range, -25 to +60 ºC (-13
to 140 ºF)
• Built-in by-pass on all sizes, saving energy and reduc-
ing installation time
• Potentiometer settings
• Run signal relay on all devices
• TOR signal relay on PSR25 … PSR105
• Optional fieldbus communication using Profibus,
Modbus, Devicenet or CANopen
• DIN rail mounting on PSR3 … PSR45
• Screw mounting on all sizes
• Connection kits for easy connection with ABB manual
motor starters
• Sophisticated algorithm eliminating the DC-component
and thereby providing excellent starting performance.
Settings
1 Start = 1 ... 20 sec
1
Stop = 0 ... 20 sec - including the step down voltage.
2 Step down = 2% reduction for each second increased stop ramp
2
Stop ramp 10 sec -> Step down 80% (20% reduction)
3 U_ini = 40 ... 70% results in End voltage = 30 ... 60%

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.
Suitable for stopping pumps
Even without using torque control, the PSR range is designed to
reduce water hammering and will allow a superior stop com-
pared 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 cor-
responding 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 softstarter - everything that you need.
