DEMOUNTABLE TRANSFORMER KIT SA742
Inspire has re-designed the classic demonstration apparatus to significantly improve safety over conventional designs. Traditional models could inadvertently generate dangerous voltages if incorrect primary-secondary coil combinations were used. To address this, Inspire’s purpose-designed power supply ensures that no combination of coils can exceed a safe 25V AC output.
Additionally, specially designed coil wings prevent any configuration that might produce high secondary voltages. The 25V AC output terminal is uniquely compatible only with specially designed coils and connectors, eliminating the risk of using standard coils to create a step-up or step-down transformer. This thoughtful redesign ensures the apparatus is both versatile and secure, providing peace of mind during demonstrations and experiments.
