This demonstration transformer helps students understand how an alternating current in the primary circuit produces an alternating magnetic field in the core, which induces an alternating current in the secondary circuit through electromagnetic induction.
The apparatus demonstrates the relationship between the number of turns in the primary and secondary coils and helps explain the basic difference between step-up and step-down transformers.
It includes one main coil with 2400 turns, designed for operation at 230–240 V, 50 Hz.
Two interchangeable secondary coils are provided, with 65 turns and 130 turns, providing outputs of approximately 6 V and 12 V respectively.
The laminated iron core consists of two sections, an 'I' section and a 'U' section, fitted with butt joints.
A simple clamping and winding arrangement allows easy assembly and interchange of the coils.
The coils are wound on insulated bobbins, with a 2-pin connection for the mains supply and a 4 mm socket for secondary outputs.
The number of turns, voltage, and amperage are clearly marked on each coil.
The transformer is supplied complete with 2 m of flexible lead and a 2-pin mains connector.
Manufactured by Atico Export to meet the practical demands of modern laboratory environments.
