Solar Demonstration Kit

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.

The classic demonstration transformer apparatus is added with some additional safety features. Rather than the traditional mains (220-230V AC) coil we have designed a dedicated Demonstration Transformer Power Supply with fixed (25V AC) voltage and high current output to which 100-turn or 150-turn mains coil substitutes connect. The advantage is that no lethal mains voltage is involved, instead the voltages to these mains coil replacements is 25V AC and so safe. Additional AC and DC outputs are provided up to 4V for other experiments.
