12-0-12 Centre Tap transformer has 240 primary windings and center tap secondary winding. It acts as a step-down transformer and reduces AC ? 240V to AC-12V. it can give outputs of 24v 12V and 0V. A transformer transfers energy on the principle of mutual induction by inductive coupling between its windings and its static device. Its core is made up of high permeability silicon steel. steel has permeability many times compared to free space and it serves to reduce magnetizing current greatly and confine the flux to a path which couples the windings.

Applications of Center Tapped Step Down transformer

Rectifier circuits

AC-AC step down

Full-wave rectifiers

Transformer Terminal Description

Terminal Name

Description

1

I1 and I2

These are the input wires for the transformer it is connected to the phase and neutral of AC main

2

T1 and T3

There are the output terminals of the Transformer the voltage across it will be 24V AC

3

T2

This is the center-tapped wire of the transformer; this wire can be combined with either T1 or T3 to get 12V AC across it. It?s very useful for rectifier circuits
