Study case of a transformer Démotransfo

This briefcase allows you to carry out numerous experiments around the transformer. Built around a sturdy and detachable U-core, you can adjust the choice of coils used to adapt the transformation ratio. The mains coil avoids the use of an external power supply, but you can also use an external SELV power supply.
