Product Code : SCL-EAE-11325
The AC Step-Down Power Unit is an educational transformer used to convert a higher AC input into a lower AC output for supervised physics and electronics experiments. It is intended for schools, colleges, universities, and technical institutes that need a reusable low-voltage AC source.
Product Description
The unit transfers electrical energy between primary and secondary windings by electromagnetic induction. It reduces AC voltage according to the winding ratio. Depending on the model, the secondary may provide one fixed output, several taps, or a centre-tapped output.
The product record identifies a bench-top educational transformer for repeated laboratory use. Housing material, terminal configuration, protection, duty rating, and galvanic-isolation status require confirmation. The unit complements other electrical and electronics laboratory equipment used in structured classroom practicals.
Key Features
- Reduced-voltage AC supply: Provides a lower AC output for compatible educational circuits.
- Transformer-based operation: Supports direct study of step-down action and electromagnetic induction.
- Reusable laboratory source: Supplies repeated practical sessions without relying on disposable cells.
- Flexible experiment support: Suitable for transformer-ratio, rectifier, lamp, coil, and AC investigations.
- Bench-top format: Intended for supervised educational use.
- Selectable output options: Fixed, tapped, or centre-tapped output is available subject to model confirmation.
- Specification-led selection: Input, output, current, and VA ratings can be matched to the experiment after verification.

Frequently Asked Questions
What is an AC step-down power unit used for?
It converts a higher AC input into a lower AC output for compatible transformer, induction, rectifier, lamp, coil, and introductory circuit experiments.
What output voltage does this unit provide?
The exact secondary voltage and tapping arrangement are [confirm]. Check the product nameplate and approved datasheet before connecting a load.
Does it convert AC to DC?
No. A transformer supplies AC output. DC requires a separate rectifier and, where needed, filtering or regulation.
Does the unit provide electrical isolation?
Isolation depends on the winding construction. Do not assume the output is isolated unless galvanic separation is explicitly confirmed for the supplied model.
What does the VA rating mean?
The VA rating states the permitted apparent-power load. The connected voltage and current must remain within the confirmed transformer rating.
Can students use it in a school laboratory?
Yes, it is intended for supervised educational work when the circuit, supply, load, and measuring instruments match the unit's verified ratings.
Request the confirmed input, output, current, VA capacity, protection, and isolation details, then browse the Electrical and Electronics Equipment category for compatible laboratory apparatus.
