Multitap Transformer
Product Code : LSK-PL-10278
Multitap Transformer (SKU LSK-PL-10278) is a low-voltage AC supply for circuits that need a high current, with outputs tapped at 0, 2, 3, 8 and 12 V. It can power heaters, lamps and coils in school and college physics labs without tying up a bench power supply. Built in the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, it is quoted straight to schools, colleges, contractors and distributors.
Specifications
Each rating of the multitap unit appears as its own row below. In brief, five AC tappings from 0 to 12 V each have a 4 mm socket, the output is rated 6 A continuously or 8 A for up to one hour, and the transformer sits in a robust powder-coated metal case weighing 3.3 kg.

Applications and Experiments for the Multitap Transformer
The transformer gives a fixed, low AC voltage with enough current for heating and electromagnetism work, freeing the bench power supply for other tasks. It can run low-voltage immersion heaters, lamps and coils in electricity, heat and magnetism practicals in secondary schools, polytechnics and college physics labs.
- Class 10 physics: heating effect of electric current.
- Specific heat capacity work with a 12 V immersion heater on the 12 V tapping.
- Taking each output to the circuit with Connecting Leads with 4 mm Safety Plugs.
- Checking the voltage of each tapping on the AC range of a Digital Multimeter.
Standard Scope of Supply
Each Multitap Transformer is supplied as a single unit in its powder-coated metal case, with a 4 mm output socket fitted for each of the 0, 2, 3, 8 and 12 V tappings. Connecting leads and the heaters, lamps or coils it will power are separate products that can be quoted with it.
Packing, MOQ and Lead Time
Ask for a quotation for one transformer or for enough to put one on every bench; each quotation lists the packing, delivery time and price for the quantity you specify. Immersion heaters, lamps and leads for school physics lab equipment in India can be added to the same enquiry.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter able to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. To have the transformer priced, message the team on the contact page, list it in the enquiry cart, or follow the formal route on the lab tender page.
Frequently Asked Questions
What output voltages does it give?
It gives low-voltage AC outputs tapped at 0, 2, 3, 8 and 12 V, each on its own 4 mm socket. Choose the tapping that suits the heater, lamp or coil connected to it.
How much current can it deliver?
The rated output is 6 A continuously, or up to 8 A for up to one hour, which suits circuits that need a high current at low voltage, such as heaters and coils.
Is Science Lab Supplies the manufacturer or a trader?
This transformer is built in the company’s own factory in Saha, Ambala, India, so Science Lab Supplies is its manufacturer. Buyers deal with the maker directly, and quotation, packing and dispatch are handled by one company.
Is the output AC or DC?
The tappings give AC only, at 0, 2, 3, 8 and 12 V. Where an experiment needs direct current, a separate DC supply can be added to the same quotation as the transformer.
