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.

Hi, thanks for the info! It consists of two or more coils of insulated https://depositphotos.com/vectors/guilloche.html wire wound around a laminated iron core. The primary coil is connected to the power source and the secondary coil is connected to the load. When an alternating current flows through the primary coil, it creates a changing magnetic field in the core, which induces a current in the secondary coil.
