Three-phase Mobile Transformer (Product Code: SLE/EPS/05) is a three-limb, three-phase teaching transformer used to demonstrate transformer theory and winding connections in electrical engineering and polytechnic laboratories. Its windings work at one volt per turn, so the no-load secondary voltage equals the number of secondary turns — something students can check for themselves. It is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and technical educational equipment manufacturer, at its own factory in Ambala, India.
| Parameter | Detail |

| Volts per turn | One volt each turn (no-load output voltage equals the number of secondary turns) |
| Tappings | Selection of high-voltage (primary) and low-voltage (secondary) tappings for a range of input and output voltages |
| Terminals | All tappings connected to coloured, shrouded sockets for safety |
| Winding connections | All tappings accessible, so windings can be linked to suit any of the common three-phase connections |
| Enclosure | Steel enclosure with small wheels for ease of mobility |
| Product code | SLE/EPS/05 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
Students use the Three-phase Mobile Transformer to explore transformer principles with values they can predict. Because each turn produces one volt, the expected no-load output of any secondary tapping is simply its turn count, so turns-ratio and voltage-ratio exercises are quick to verify with a meter.
With every tapping on its own shrouded socket, groups wire the primary and secondary windings to suit the experiment — including the common three-phase connections such as star and delta — and compare line and phase voltages. The wheeled steel enclosure lets one unit move between benches, or into a lecture room for demonstrations. Always isolate the supply before changing connections.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Three-phase Mobile Transformer. Each unit is made at the company’s own licensed factory in Saha, Ambala, Haryana, India, and sold factory-direct, so colleges, training centres, dealers and importers get quotations and after-sales answers from the maker rather than a middleman.

Why does the Three-phase Mobile Transformer work at one volt per turn?
The Three-phase Mobile Transformer is wound at one volt per turn so that its no-load output voltage equals the number of turns on the secondary. Students can predict output voltages from turn counts and check transformer principles clearly.
Which three-phase connections can students make?
All tappings of the Three-phase Mobile Transformer are accessible, so students can link the primary and secondary windings to suit any of the common three-phase connections. Each tapping ends in a coloured, shrouded socket, keeping the wiring clear and safer.
How is the Three-phase Mobile Transformer built?
The Three-phase Mobile Transformer uses three identical transformers on a common core, forming a three-limb, three-phase transformer. It sits inside a steel enclosure with small wheels, so it moves easily between benches or rooms.
Can it give different input and output voltages?
Yes. The Three-phase Mobile Transformer has a selection of high-voltage (primary) and low-voltage (secondary) tappings for a range of input and output voltages. Share the voltages you need through our contact page so we can confirm suitability.
Who manufactures the Three-phase Mobile Transformer?
The Three-phase Mobile Transformer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Orders, spare parts and technical questions are handled by the manufacturer itself.
Is the transformer available for export?
Yes. ScienceLab supplies the Three-phase Mobile Transformer to colleges, institutes and dealers in India and international markets. A quotation request should give the quantity, your three-phase supply and the input and output voltages you plan to use.
