Laboratory AC Supply Transformer

Product Code : SCL-EAE-11322

The Laboratory AC Supply Transformer is an educational step-down power unit used to provide low-voltage alternating current for supervised physics and electronics experiments. It allows compatible laboratory circuits to be operated from a controlled secondary supply while keeping the experimental voltage below the transformer’s primary input level.

Product Description

The apparatus uses electromagnetic induction to transfer AC power between primary and secondary windings. Depending on the confirmed construction, its secondary winding may provide a single low-voltage output, multiple fixed taps or a centre-tapped supply. These outputs can support rectifier, transformer-ratio, lamp, coil and introductory AC-circuit investigations.

A laboratory transformer should be selected according to its primary input, secondary voltage, continuous current and apparent-power rating. An isolation transformer may separate the experimental secondary circuit galvanically from the mains input, but isolation must not be claimed unless the winding arrangement and safety documentation are confirmed for the exact model.

Key Features

• Low-voltage AC output: Intended to supply compatible educational experiments at reduced voltage.
• Step-down transformer operation: Demonstrates electromagnetic induction and transformer action.

How to Use

1. Place the transformer on a dry, stable and ventilated bench.
2. Confirm that the primary input matches the available laboratory supply.
3. Keep the input switch off while connecting the secondary circuit.
4. Select the required secondary terminals or voltage tap.
5. Connect the load and suitable AC measuring instruments.
6. Switch on the transformer and observe the secondary voltage.
7. Keep the connected load within the confirmed current and VA ratings.
8. Switch off and disconnect the unit before changing connections.

Safety note: The primary side may contain hazardous mains voltage. Do not open the enclosure, touch exposed conductors, exceed the secondary rating or assume the output is isolated unless galvanic isolation is explicitly confirmed.

Care & Maintenance

• Keep ventilation openings and terminal surfaces clean.
• Inspect the mains cable, plug and output sockets regularly.
• Replace fuses only with the specified type and rating.
• Disconnect the unit before cleaning, inspection or storage.

Frequently Asked Questions

What is a Laboratory AC Supply Transformer used for?

It provides reduced-voltage alternating current for transformer, induction, rectifier and introductory AC-circuit experiments.

What secondary voltages are available?

The exact secondary voltage and tapping arrangement are not published for the requested unit.

Does the transformer provide electrical isolation?

Isolation depends on the winding construction. It must not be assumed without confirmation that the primary and secondary are galvanically separated.

What does the VA rating indicate?

The VA rating defines the transformer’s permitted apparent-power load and must be considered together with the selected secondary voltage.

Can it power rectifier experiments?

Yes, when its secondary voltage, current rating and tapping arrangement match the rectifier circuit requirements.

Does it include overload protection?

No product-specific fuse, current-limit or thermal-protection arrangement has been verified.
