WITH A DRIVE ISOLATION TRANSFORMER, LOAD DISTURBANCES CAUSED BY THE SCR DRIVE ARE MINIMIZED
A transformer is needed to magnetically isolate incoming lines on Silicon Control Rectifier (SCR) variable speed motor drive applications. For the required voltage of the SCR drive to match a transformer must also provide a voltage change. In the majority of three phase rectifier circuits, standard designs of delta primary and wye secondary match the common power sources required for three phases. With Sola Heavy-Duty drive isolation transformers, you are assured the voltage demands and harmonics associated with SCR applications will be addressed because they are specifically designed to handle that type of mechanical stresses.
