The most common type of control transformer has two primary coils and one secondary coil, as shown in Figure 1.9. Figure 1.9: A Typical Control Transformer Configuration. In most cases, the control transformer is used to reduce the main or line voltage of 240 VAC or 480 VAC to a control voltage of 120 VAC. Notice that the primary windings are ...
