This Technical Guide aims to give a basic understanding of the technologies and practices presently available to those considering purchasing 'standard' medium-voltage AC drives.

However, in a Technical Guide of this nature it is not possible to give an in-depth analysis of all aspects of selecting, purchasing, installing and commissioning medium-voltage AC drives. The reader is advised to call Technicon who is an authorized ABB distributor and we will get your more detailed questions answered.
