I would like to reuse the autotransformer of this device, which converts 220 to 110 and claims to be bidirectional.
This transformer has 0-220V inputs and 3 output wires. One goes to a diode in the PCB, the other one is output, the third goes through a relais which then goes to outputs.
It seems to be a common design in these kind of converters but I can post more photos if needed.
Do you guys know if the autotransformer in these step-down can be used for straight 220-110V conversion, bypassing the circuit?
