Motor Drive Isolation Transformer
With today’s technological advances in solid-state power control devices, AC and DC variable speed motor drives have become more popular in many industrial applications. Siemens Drive Isolation Transformers are designed to meet the rugged demands of AC and DC variable speed drives and to provide circuit isolation from SCR’s. They also provide the specific horsepower rating and voltage change to match the motor drive system. The cores are designed with reduced flux density to meet the inrush characteristics of drive applications. Windings are braced to withstand the mechanical stress and overload capacity needed for motor drive and SCR duty cycles. The separate primary and secondary windings provide electrical isolation between the incoming line and the load which minimizes line disturbances, feedback, and transients caused by SCR firing.
