Featuring a 230V primary input and a center-tapped 9-0-9V output, it supports up to 750mA current, making it ideal for compact PCB installations and versatile applications including robotics and educational projects. ## Description 9-0-9 750mA Center Tapped Step Down Transformer is a general-purpose chassis mounting mains transformer. The transformer has 230V primary winding and center-tapped secondary winding. The transformer has flying-colored insulated connecting leads ( Approx 100 mm long ). The Transformer act as a step-down transformer reducing AC - 230V to AC - 9V.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.
