Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the unit is presented as separate DC motors and AC generators not assembled as a single converter
Separate motors and generators are classified individually under heading 85.01.
If the conversion is performed by static power electronics instead of a rotating machine
Static converters are classified under heading 85.04.
