Description
Drive Isolation Transformers are designed for SCR (Silicon Control Rectifier) variable speed motor drive applications where 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.- Part Number
