    What is a Step-Down Transformer? (.PDF Download)

    Aug. 27, 2020

    Transformers are static electrical devices with no moving parts, transforming electrical power from one voltage and current setting to another. The frequency of the electrical current remains constant.

    Transformers are classified by their function, which is either step up or step down. Step-up transformers increase the voltage of the incoming current, while step-down transformers decrease the incoming current’s voltage. The incoming voltage is referred to as the primary voltage, while the outgoing stream is referred to as secondary.
