Step Down Transformer
Product Code : SCL-EAE-11259
Quick answer: This Step Down Transformer is a teaching transformer that lowers an alternating input voltage to a smaller output voltage by mutual induction. Students compare primary and secondary AC voltages, relate them to the winding ratio and discuss transformer losses and efficiency. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the transformer is used in teaching
An alternating current in the primary winding produces a changing magnetic flux in the core, and this changing flux links the secondary winding and induces an alternating voltage in it. The voltages follow the turns ratio, Vs/Vp = Ns/Np, so a step down transformer has fewer turns on its secondary than on its primary. For an ideal transformer the power in equals the power out, Vp Ip = Vs Is, so the secondary current is larger than the primary current.
- Place the transformer on a stable, dry, non-conductive surface.
- Check the nameplate and make sure the AC supply matches the input rating.
- Keep the supply switched off while making all connections.
- Connect AC voltmeters across the primary and the secondary, then switch on.
- Record both voltages, then repeat with a suitable load to observe the output under load.
Comparing the measured voltage ratio with the turns ratio, and the output power with the input power, introduces copper and iron losses and the idea of transformer efficiency.

Frequently asked questions
What does a step down transformer demonstrate?
It demonstrates mutual induction and the turns-ratio rule: the secondary, with fewer turns, gives a lower AC voltage than the primary.
Does a transformer work on DC?
No. A steady direct current produces no changing flux, so no voltage is induced in the secondary. A transformer needs an AC input.
What is the price of the step down transformer?
