Application of soft starter

- Aug 06, 2019-

Soft starter is easy to install and adjust, all control connections and parameter adjustment are completed on the front.After installation, the soft starter can be easily modified in place, such as additional current limiting function and internal/external connection conversion.The soft starter is continuously online without bypass.The soft starter has separate control relays for bypass and fault.All parameters of the soft starter are set by three knobs potentiometer and one dial switch on the panel, which is intuitive and accurate.It can even work in applications where vibration and ambient temperature are high.When the soft starter is used for internal connection, because the thyristor module is subjected to the phase current of triangular connection, the soft starter with the same current can load the motor 1.73 times larger than that of external connection.For example, an s-type soft starter of 58A can load a motor of 100A when it is connected internally.

In principle, cage asynchronous motors can be used in all kinds of applications where speed regulation is not required.The range is 380V ac (or 660V), with motor power ranging from a few kilowatts to 800 kilowatts.Soft starter is especially suitable for all kinds of pump load or fan load, need soft start and soft stop.It can be widely used in textile, metallurgy, petrochemical, water treatment, shipping, transportation, medicine, food processing, mining and mechanical equipment and other industries.
