What voltage step-up is achievable with a control transformer?

A control transformer is designed to step down or step up voltage based on specific application requirements, commonly in control systems. The correct response reflects that a control transformer can convert the rated input voltage to a determined output voltage.

This characteristic allows users to achieve the desired voltage level that meets operational needs, such as providing lower control voltages from higher supply voltages. Each transformer has specified ratings for input and output, defining the voltage that it can manage while maintaining safety and performance. This capability makes control transformers essential in electric motor control systems for ensuring that the equipment operates efficiently and safely within the required voltage specifications.

The other choices do not accurately represent the functionality of control transformers. They either imply unrestricted voltage transformations or incorrectly state specific limits without considering the operational capabilities of commercially available transformers.
