Type PSR is the latest addition to the ABB Softstarter family, and has an
attractive, compact design. With this compact design, the PSR Softstarters
are ideal for installation in places where space is limited and where there
is a demand for easy installation.
- Main voltage 208 – 600 V
- Current ratings 3.9 – 45 A
- Supply voltage 24 V DC or 100-240 V AC
- DIN rail or screw mounting
- Integrated by-pass contacts
 PSS
- The Flexible Range
Type PSS offers a very flexible solution with easy installation and setup.
With the flexible design you can select between installing inside delta or
in line with the motor. And if you need the function current limit, you can
activate this adding an external current transformer.
- Main voltage range 208 – 690 V AC
- Current ratings 18…300 (In Line) and 30 … 515 A (Inside
Delta)
- Supply voltage 110 – 120 V AC and 220 – 240 V AC
- Same unit can be used for both In Line and Inside Delta
connection.
- Start ramp, Stop ramp and Initial voltage included
 PST
(B) - The Advanced Range
Type PST(B) range covers almost all your needs for starting, controlling and
protecting your motors. The PST(B) softstarters are very easy to set up
using the multi language interface. For both starting and stopping the motor
we offering two alternative settings, voltage ramp or the new torque control
where torque control gives an excellent soft stop for pumps among others.
They also include several advanced protections, programmable in and out puts
and BUS communication, all as standard. The sizes PSTB370 to 1050 has a
by-pass contactor built in.
- Main voltage 208V – 690V AC
- Current ratings 30…1050 (In line) and 52…1810A (Inside
delta)
- Supply voltage 100 – 250V AC
- Advanced motor protection,
- Flexible bus communication system for Profibus,
Devicenet and Modbus
- Analog output
- Torque Control, an alternative to Voltage ramp
