Step Down Transformer Model
Product Code : SCL-PLE-11619
Quick Answer: The Step Down Transformer Model takes 220V AC mains and gives a 12V AC output, using a many-turn primary and a few-turn secondary of copper wire on a laminated core, to show how mains voltage is reduced by induction.

Key Features
- 220V AC mains input, 12V AC output.
- Primary coil with more turns than the secondary.
- Copper windings on a laminated L-core/U-core.
- Mains cable for the input and socket terminals for the output.
Technical Specifications
| Specification | Value |
|---|---|
| Input | 220V AC mains |
| Output | 12V AC |
| Coils | Primary (high turns), secondary (low turns) |
| Winding | Copper on laminated L-core/U-core |
| Connections | Integrated power cable (input), socket terminals (output) |
How It Is Used
With the model plugged into the mains, the 12V AC output at the sockets can be measured with an AC voltmeter and compared with the input. The coil arrangement illustrates the transformer relation Vp/Vs = Np/Ns, with fewer turns on the secondary giving the lower voltage.
Frequently Asked Questions
