Single-phase short circuit proof autotransformer designed and tested according to EN61558-2-13. No galvanic separation between primary and secondary voltage. Insulated windings moulded in self extinguishing Polyurethane and capsulated in plastic. This protects the transformer against hostile environment such as dust, humidity and corrosion. For fixed installation, simple and easy mounting. Short circuit protected with glass tube fuse and overload protected with "cut out" fuse. Use the A-P models to change voltage from 400 to 230 Volts, 230 to 110 Volts or vice versa. Supplied with a large number of tappings/ adjustments for several stages desired. Custom designed models on request.
