PSR – The compact range
Description
Product description
• Wide rated operational voltage 208–600 V
• Rated control supply voltage 24 V AC/DC or 100–240 V AC
• Rated operational current 3–105 A
• Wide ambient temperature range, -25 to +60 ºC
• Built-in by-pass on all sizes, saving energy and reducing
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’s manual
motor starters
• Sophisticated algorithm eliminating the DC-component and
thereby providing excellent starting performance
The PSR range is the most compact of all ABB’s softstarter
ranges. The compact PSR range makes it possible to fit many
devices into the same enclosure. A PSR together with a MMS
(manual motor starter) makes up a far more compact starting
solution than a Star-Delta starter, for instance.
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 setup 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’s 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. Compared to the direct stops of a
Star-Delta starter or a DOL starter the PSR is superior. See the
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 by using
the special designed connection kits. This makes both 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.
Settings
1 Start = 1 ... 20 sec

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%
