DEMOUNTABLE TRANSFORMER KIT SA742

Inspire have redesigned the classic demonstration apparatus to address the safety issues in the conventional apparatus. The conventional design always had the chance to generate lethal voltage if a wrong primary -secondary combination of coils were used. Using the purposedesigned power supply, no voltage greater than 25V ac can be experienced in whatever cobination of primary – secondary coils the user selects. Also, the wings of the specially designed coils prevent any wrong combination to generate high secondary voltage. The 25 V ac output terminal of the power supply cannot be connected across the ordinary coils to make step-up or step-down trnasformer and hence safe. Only specially designed coils with special connectors joins to the 25V ac terminal.
