ABB PSR Softstarter - a smart softstarter.
ABB Automation Products serves customer worldwide and has
long experience and comprehensive know-how of the developement
and production of softstarters.
After the PSS and the PST(B) ranges, it is now time to introduce
the small compact PSR Softstarter - a real smart starter.

The Softstarter is the solution to both
mechanical and electrical problems.
Constant-speed AC motors are the workhorses of industry; they are
used to drive fans, pumps, conveyors and lots of other types of
machinery. These motors are tough machines, but they have some
drawbacks. During start and stop both mechanical and electrical
stresses are high, causing undesirable load peaks each time the
motors are started. An ABB Softstarter eliminates many of these
problems. The voltage is smoothly applied to, and removed from,
the motor. Both the torque and the current consequently behave in
the same way. The result is that mechanical and electrical stresses
are signifi cantly lower than with conventional starting methods.
Fewer electrical problems-
The starting current will be signifi cantly lower than with direct on
line (DOL) starting and compared with Y/D starters the switching
transients will be eliminated.
Fewer mechanical problems-
Sliding drive belts and gearbox wear caused by heavy torque peaks
are familiar problems that require lots of maintenance. PSR Softstarter
reduce the torque peaks as the apply the torque smoothly.
Fewer operational problems-
Pressure surges in pipelines are often called water hammer. It is
a common but undesirable effect when stopping almost all pumps.
PSR Softstarters allow smooth stops and reduce the problems
associated with water hammer. |

ABB softstarters - Advanced, Flexible and Compact Range
ABB offers three different ranges of softstarter to cover every customer
need for solutions for small to medium-sized motor applications.
PST(B) - Advanced range, covers motor currents from 30 to 1050 A
and provides advanced functionality, including integrated protections,
programmable signal relays, a flexible communication system and an
LCD display. Sizes PSTB370 to 1050 A include a by-pass contactor.
PSS - Flexible range covers motor currents from 50 to 300 A and
offers a fl exible solution with easy installation and setup. It can also be
connected in-line or inside delta.
PSR - Compact range, covers motor currents from 3 to 45 A. It is the
latest addition to the softstarter family and has an attractive, compact
design. Further, the system concept includes MMS and the softstarters
are available for remote control connection using the FieldBusPlug as
an accessory. All sizes include a Run signal relay, while from sizes
25 A the PSR Softstarters are also provided with an output signal for
TOR (Top Of Ramp), i.e. full voltage. With standard performance the
PSR Softstarters handle ten starts per hour. When an auxiliary cooling
fan is added, the starting capacity is increased to 20 starts per hour.
• Current ratings 3.9 - 45 A (1.5 - 22 kW)
• Motor voltage 208 - 600 V
• Supply voltage 24 V DC or 100 - 240 V AC
• Easy to install and adjust
• DIN rail or screw mounting
With their compact design, the PSR Softstarters are ideal for installation
in places where space is limited and where there is a demand for easy
installation.
