Step Down Transformer
Product Code : SCL-EAE-11207
Quick answer: The Step Down Transformer converts 220-240 V AC mains to low AC voltages of 2, 4, 6, 8, 10 or 12 V, selected with a rotary dial, at up to 2 A. It powers lamps, coils and circuit boards in physics practicals and is used to show the transformer turns-ratio rule. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the transformer is used
A transformer works by mutual induction: an alternating current in the primary coil sets up a changing magnetic flux in the core, which induces a voltage in the secondary coil. For an ideal transformer Vs/Vp = Ns/Np, so a secondary with fewer turns than the primary gives a lower voltage. The selector on this unit gives six output steps from 2 V to 12 V.
- Place the transformer on a dry, level bench away from water.
- Set the selector to the lowest output and connect the load to the output sockets.
- Connect the mains lead and switch on; the LED confirms that the unit is live.
- Raise the output step by step as the experiment requires, keeping the load current at or below 2 A.
- Switch off at the mains before changing connections.
Because the output is AC, it suits lamps, heating coils, induction and electromagnet demonstrations directly; for DC experiments a rectifier or a battery eliminator is used instead.

Frequently asked questions
What output voltages does the step down transformer give?
It gives 2, 4, 6, 8, 10 and 12 V AC, selected on a rotary dial, with a maximum current of 2 A from a 220-240 V, 50 Hz mains input.
Can it be used for DC experiments?
Not directly, because the output is AC. For DC work, use a battery eliminator or a rectifier circuit between the transformer and the load.
