Products in this family are used in conjunction with AC utility power, for safety or functional reasons. Isolation transformers are used to transfer electrical power without the use of a galvanic electrical connection, and are commonly used in repair or product development environments to mitigate shock hazards. Autotransformers are used for scaling the voltage of an available source up or down to meet a functional requirement when isolation between input and output is not required.
