Drive Isolation Transformers are used to supply power to AC and DC Variable Frequency Drives. These transformers are used to magnetically isolate the incoming line from the motor drive while still providing a voltage change to match the required voltage of the SCR (Silicon Control Rectifier) Drive. The mechanical stresses, voltage distortions and harmonics created by SCR type drives require robust mechanical and electrical design and testing. 

MGM Transformer has designed and constructed Drive Isolation transformers for decades and supplies Drive manufacturers in some of their most challenging applications.
