PSR softstarter – The compact range

The PSR softstarter range is a simple yet reliable starting solution that utilizes only the most basic of soft starting features: soft start and stop. It performs well in applications requiring many starts per hour and is perfect for installations where you need to save space. Main benefits
  • Small and compact starting solution
  • Can perform many starts per hour
  • Reduce energy loss at full speed with built-in bypass.
Main features
  • Rated operational current: 3 to 105 A
  • Operational voltage: 208–600 V AC
  • Control supply voltage: 24 V AC/DC or 100–240 V AC.

PSR – The compact range

Introduction

The PSR softstarter is the most compact of all the softstarter ranges, which allows for the 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
− Operational voltage: 208…600 V AC
− Wide rated control supply voltage:
100…240 V AC, 50/60 Hz or
24 V AC/DC
− Rated operational current: 3…105 A
− Soft start with voltage ramp
− Soft stop with voltage ramp
− Built-in bypass for energy saving and easy installation

− Easy set-up by three potentiometers
− Fieldbus communication with FieldBusPlug adapter and the FieldBusPlug
− Run and Top of Ramp relays available for monitoring
− Connection kits available for connection to ABB manual motor starters (MMS)

Secure motor

Reliability

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

Improve installation

Efficiency

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 installation and providing more space in your panel. Set-up is done through three potentiometers making it very fast and easy

Increase application

Productivity

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

Motor protection with manual motor starter

Use the PSR together with the MMS to get a complete motor starter with soft start and stop together with overload and short circuit protection.

Connection kit (optional)

The connection kits simplifies installation of the PSR by making the connection to the MMS screwless.

Screw or DIN-rail mounted

PSR is fast and easy to install by using screw mounting or DIN-rail mounting (PSR3…PSR45).

Output signal relays

PSR has output relays for Run and Top of ramp (PSR25…PSR105).

LED indicators

PSR has LED indicators for On/Ready and Run/Top of ramp.

Three potentiometers for settings

Set-up is made very easy with only three potentiometers, for start ramp time, stop ramp time and initial/end voltage level.
