DT631H275S 275VA 3 Phase Drive Isolation Transformer

DT631H275S 275VA 3 Phase Drive Isolation Transformer

For SCR (Silicon Control Rectifier) variable speed motor drive applications, a transformer is needed to magnetically isolate the incoming line from the motor drive. The transformer must also provide a voltage change to match the required voltage of the SCR Drive. Standard designs are delta primary and wye secondary to match the common power sources required in most three phase rectifier circuits.
