Portable autotransformer for changing system voltage.

Autotransformers are not able to eliminate earth faults, all earth fault problems will be propagated through the transformer, resulting in a considerable risk to safety. The use of autotransformers is therefore not permitted in ships and medical installations. Custom designed models on request.
