3 Phase Auto Transformers

POWERTRONIX 3 Phase Auto Transformers
These transformers are for voltage step up or step down when there is no requirement for electrical isolation. Auto Transformers offer a significant size and weight reduction as well as lower cost. Powertronix three phase systems are available for Delta-Delta, Wye-Wye configurations.

APPLICATIONS
Auto Transformers are used in applications where there is no requirement for electrical insulation between input and output windings. These are popular for industrial automation and marine applications.
