The 18V-0V-18V 1Amp Step-Down Transformer is a versatile chassis-mounting mains transformer designed for general-purpose applications. Featuring a 230V primary winding and a non-center tapped secondary winding, this transformer is equipped with flying colored insulated connecting leads, approximately 100 mm in length. Its primary function is to act as a step-down transformer, reducing AC voltage from 230V to AC 18V.
Providing output voltages of 18V and 0V, the transformer’s construction involves a solid core and winding. As a static electrical device, it transfers energy through inductive coupling between its winding circuits. The varying current in the primary winding generates a fluctuating magnetic flux in the transformer’s core, creating a corresponding varying magnetic flux through the secondary winding. This flux variation induces an electromotive force (E.M.F) or voltage in the secondary winding.
The transformer’s cores are crafted from high permeability silicon steel, significantly reducing magnetizing current. The core serves to confine the flux to a path that closely couples with the winding, ensuring efficient energy transfer. This design feature enhances the transformer’s performance and reliability in various electrical applications.
