soft starter
The ABB soft starter, with its compact size and innovative design, is a novel motor control device that integrates motor soft start, soft stop, light load energy-saving, and multiple protection functions. It can achieve fieldbus control and is easy to set and debug. Its main components are three-phase anti parallel thyristors and their electronic control circuits connected in series between the power supply and the controlled motor. By using different methods to control the conduction angle of three-phase anti parallel thyristors, the input voltage of the controlled motor can be varied according to different requirements to achieve different functions. All boundaries are at the forefront, reducing installation time and lowering maintenance costs.
