ABB offers four models of soft starters to meet various application needs, with motor currents ranging from 3A to 1810A. The product series includes the intelligent PST (B) series and the easy-to-use PSE series
Column, universal PSS series, and compact PSR series.
ABB PSTB soft start
Soft starter
When the first electric motor appeared, engineers had been searching for a way to avoid it
Electrical and mechanical issues that occur during the start-up of an electric motor. Since the early 1980s,
ABB has been producing soft starters and has valuable experience. Nowadays, these classics
Testing is also integrated into the design of product lines. The latest PST series launched by ABB is
A significant advancement in soft start technology. Applied intelligence from modern power electronics
The soft starter developed by ABB can use electronic components excellently in both circuits and software
To control the current and voltage during the starting and stopping of the electric motor, several additional components have been added
Design features.
Solutions to mechanical and electrical issues
AC electric motor - known as the "industrial pack horse", used to drive fans, crushes
Equipment such as machines, mixers, water pumps, conveyor belts, etc. In production factories around the world,
It often causes unnecessary torque and current peaks, while also causing various losses
Bad, including: electrical issues
The sudden changes in voltage and current generated during direct starting or star delta starting have caused significant impacts
Electrical issues related to quantity. These sudden changes may cause overload of the local power grid and result in
Unacceptable voltage fluctuations that affect other devices connected to the power grid.
Electric motor voltage
Direct start star/triangle start soft start
Adjustable starting point
Mechanical problems with dynamic slope curves
The entire transmission chain (from the electric motor to the driven equipment) will be subjected to severe stress,
Causing a large amount of maintenance work and even parking accidents. Operational issues
Such as pressure in pipelines, damage to products on conveyor belts, and discomfort for personnel riding elevators.
Water hammer effect and pipeline pressure fluctuation issues
Water hammer effect and pipeline pressure fluctuations often occur during the process of starting and stopping water pumps.
Behind every technical issue and malfunction, attention should be paid to the economic losses caused by maintenance and production stoppage.
A simple way to solve these problems is to install ABB's PST (B) soft starter. Got it
ABB soft starter can smoothly start and stop the motor, maximizing its performance
Reduce mechanical and electrical impacts.

common problem
How to avoid voltage drop in the power grid during the start-up process?
ABB soft starter can reduce the starting current during the starting process, thereby avoiding voltage drop problems.
How to avoid water hammer effect during the parking process of the water pump?
ABB soft starters can optimize parking slope curves and reduce water hammer effects. Or adopt
The torque control function better solves such problems.
How to ensure reliable operation of equipment in harsh environments?
ABB soft starters use control boards with protective coatings to ensure safe and reliable use of the equipment.
How to ensure the safety of the water pump during use?
The ABB soft starter is equipped with a unique design of pump protection functions, such as overload protection, underload protection, and rotor stalling protection.

Compressor type load
Conveyor belt load
Fan type load
common problem
How to ensure the service life of the compressor?
ABB soft starter can reduce the acceleration torque during the starting process, thereby reducing mechanical stress.
How to build a compact compressor unit?
Using ABB compact soft starters (PSR or PSE series), compared to traditional star delta starters, can enable customers' starting control
The manufacturing unit is more compact.
common problem
How to avoid the pressure drop generated during the start-up process for a long time?
ABB soft starter is equipped with limited current function, which can control the starting current and reduce the impact of voltage drop.
How to extend the lifespan of the transmission belt?
ABB soft starter can reduce excess mechanical tension during the starting process and prevent belt looseness.
How to ensure the safety of fan equipment during use?
The underload protection function of ABB soft starter can detect belt breakage and take corresponding preventive actions immediately.
common problem
How to reduce the maintenance and repair of conveyor belts?
ABB soft starters can reduce mechanical stress during the starting process.
How to avoid the belt running in the wrong direction?
The reverse phase protection function of ABB soft starter can prevent the belt from running in the wrong direction.
How to improve the efficiency of the conveyor belt?
ABB soft starter can be equipped with high/low current alarm function to remind loading or unloading of the conveyor belt.
How to ensure that equipment that has been idle for a long time can start normally?
The sudden jump starting function of ABB soft starter can provide a short-term additional torque to overcome the high initial friction and ensure transmission
The normal start of the belt.
