Dual Voltage Transformer
A dual-voltage transformer is a type of transformer that has two different output voltages. A Dual voltage transformer has two separate winding that may be used as a single winding or can be connected in a series to get different voltage levels. When we connect the transformer winding in the series the number of turns increases and thus we get a higher voltage.
Why do we need two voltage levels? The electrical appliances operated in different regions may have different voltage standards and to meet user’s requirements, equipment manufacturers provide a dual voltage transformer with equipment so that users can select the voltage according to their electrical system requirements.
