About This Product
The transformer brings the input AC voltage down to a lower output range for school experiments. Students connect lamps, coils or circuit modules to the output and observe the circuit, keeping the total current within the 2 A rating. Besides supplying power, it is used to teach voltage transformation, primary and secondary coils and mutual induction. It is operated under teacher supervision and switched off before connections or voltage settings are changed.
Frequently Asked Questions
Q1. What can be connected to the output? Compatible lamps, coils, circuit modules and electromagnetism accessories can be powered from the 2-12 V AC output, as long as the total current stays within the 2 A rating.
