PSR – The compact range

Introduction

2 The PSR softstarter is the most compact of all the softstarter ranges which
allows for design of compact starting equipment. A PSR together with a
manual motor starter makes up a far more compact starting solution than a
star-delta starter, and with the built-in bypass, the energy losses inside the
softstarter are highly reduced.

• Two-phase controlled • Easy set-up by three potentiometers
• Operational voltage: 208...600 V AC • Fieldbus communication with FieldBusPlug
• Wide rated control supply voltage: adapter and the FieldBusPlug
100...240 V AC, 50/60 Hz or 24 V AC/DC • Run and Top of Ramp relays available
• Rated operational current: 3...105 A for monitoring
• Soft start with voltage ramp • Connection kits available for connection to
• Soft stop with voltage ramp ABB´s manual motor starters (MMS)
• Built-in bypass for energy saving and
easy installation

Reduce the electrical stresses and keep the motor protected with the MMS
Secure motor
The PSR reduces the starting current for the motor. The possibility to connect it to
Reliability the manual motor starter makes it possible to build a compact and complete starting
solution with overload and short-circuit protection.

Improve installation Saving time and money with built-in bypass and easy set-up
On the PSR, the bypass is built in and verified by ABB, saving you time during
Efficiency installation and space in your panel. Set-up is done through three potentiometers
making it very fast and easy.

Increase application Reduce the mechanical stresses on your motor
Soft start and stop with PSR will reduce mechanical wear and tear on the application
Productivity and increase the availability and uptime.
