Step Down Transformer Model STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-IMIC-12546
Quick Answer: The Step Down Transformer Model is an open demonstration transformer with a laminated silicon steel U and I core and two detachable copper coils. Low-voltage AC up to 12V on the high-turn primary gives a lower voltage on the secondary.

About This Product
Because the coils and core are exposed, students can see how a transformer is built, take it apart and reassemble it. Measuring input and output voltages, and comparing the secondary taps, lets them check the turns-ratio relationship and see that the changing flux in the core is what induces the lower voltage.
Frequently Asked Questions
What power supply should be used with the Step Down Transformer Model?
A low-voltage AC bench supply of up to 12V AC. The open model must never be connected directly to mains.
Why is the core laminated?
Laminations reduce eddy current losses in the core.
