Application

One is to save energy as the main purpose and simplify some system functions of the low-cost simple general frequency converter, it is mainly used in water pump, fan, blower and other system speed performance requirements are not high occasions, and has the advantages of small size, low price;

Second, in the design process fully considered the various needs of the application of high performance, multifunctional general frequency converter, in use, the user can according to the characteristics of the load selection algorithm to set the various parameters of the frequency converter, can also according to the needs of the system to choose a variety of spare options provided by the manufacturer to meet the special needs of the system.

With the rapid development of industrial automation, the practical work of frequency converter is more and more important.
