AC 240 V to DC 12 V 3A. This is a general purpose chassis mounting mains transformer. Transformer has 240 V primary windings and secondary winding. The transformer has flying colored insulated connecting leads .The Transformer act as step down transformer reducing 240 V AC to 12 V DC.

The Transformer gives two outputs of 12V, 12V and 0V. The Transformer’s construction is written below with details of Solid Core and Winding.

The transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (E.M.F) or voltage in the secondary winding. The transformer has cores made of high permeability silicon steel. The steel has a permeability many times that of free space and the core thus serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the windings.
