12-0-12 3 Amp Step-Down Transformer is a general-purpose chassis mounting mains transformer. The transformer has 230V primary winding and non-centre tapped secondary winding. The transformer has flying coloured insulated connecting leads ( Approx 100 mm long ). The Transformer act as a step down transformer reducing AC – 230V to AC – 12V. CityTech BD
The Transformer gives outputs of 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 serving to greatly reduce the magnetizing current and confine the flux to a path that closely couples the winding.
