Demountable Transformer
This heavy duty demountable transformer can be used for the study of transformer theory and many other alternating current phenomena. This kit consists of:
- A magnetic circuit made of highly permeable U shape metal sheet, which can be closed using two clamps with tightening screws.
- Section: 40 x 40 mm with 150 mm length and 170 mm height.
- One coil of 6000 turns with maximum current of 0.2 ampere. Intermediary coil of 2000 turns output.
- One coil of 600 turns with maximum current of 2.5 ampere, which is mainly used to create the primary of transformer.
- One coil of 1200 turns, with maximum current of 1.25 ampere, fitted with intermediary 400 and 800 turns’ outputs.
- One coil of 72 turns, with maximum current of 12 ampere, fitted with intermediary 6, 30, 54 and 66 turns’ outputs.
- Power supply cable.
