An autotransformer is an electrical piece of equipment that enables you to raise or reduce the voltage of an electrical power circuit. This enables you to go from a 3x230Vcircuit without a neutral conductor to a 3x400V circuit with a neutral conductor in your home.
The benefit of an autotransformer is that it is cheaper and smaller than a conventional transformer although it delivers a considerably lower yield.
How much does it cost? Where do I find one? Who handles the installation?
Please raise all your questions regarding the autotransformer with a qualified electrical engineer or your charging point installation company. They will help you get one and handle the installation for you.
