Käyttökohde

Single-phase short circuit proof autotransformer designed and tested according to EN61558-2-13. Insulated windings moulded in self extinguishing Polyurethane and capsulated in plastic. For fixed installation, simple and easy mounting. Short circuit protected with glass tube fuse and overload protected with "cut out" fuse on primary side.
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.
