Frequency converters are increasingly being used in electrical drive technology. These allow variable speed operation as opposed to mains-fed operation.
A basic knowledge of converters is therefore necessary for planning, commissioning and maintaining drive systems.
This training session introduces you to this subject. It gives you a basic understanding of what you need to know to achieve optimal learning results from SITRAIN courses at the training center.
