PSR Open Softstarters

PSR Open Softstarter – The Compact Range

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

Features and benefits

Two-phase controlled
Soft start and stop with voltage ramp
Built-in bypass for energy saving and easy installation
Easy set-up by three potentiometers
Output signal relays for run and top of ramp
Connection kits available for connection to ABB´s manual motor starters (MMS)
Motor Protection with manual motor starter by combining with MMS for overload and short-circuit protection

Benefits

Secure motor reliability
Keep the motor protected with the MMS. The PSR reduces the starting current for the motor. The possibility to connect it to the manual motor starter (MMS) makes it possible to build a compact and complete starting solution with overload and short-circuit protection.

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

Increase productivity
Soft start and stop with PSR will reduce mechanical wear and tear on the application and increase the availability and uptime.
