The mains voltage can be continuously adjusted with this variable AC transformer. This means that the variable AC transformer can also be used as a dimmer for the bright flashlight (1000 W). If you combine it with the isolating transformer, it is possible to continuously regulate the DC voltage in the range of 0 - 36 V.
The use of this combination does not require a "completed teaching degree in physics or comparable training courses" and is permitted for class teachers who teach physics without a physics degree.
Use: 6th - 12th grade
