Developing Control Circuits:Developing Control Circuits ...

When developing a control circuit, the logic of the circuit is developed one stage at a time until the circuit operates as desired. The first stage of the circuit is shown in Figure 48 – 1. In this stage, a control transformer has been used to step the 480 volt supply line voltage down to 120 volts for use by the control circuit.
