The Autotransformer is designed to change a wide range of mains voltages to a matching voltage of the appliance operating voltage.
These transformers are capable of adjusting voltage to higher or lower rate then the electrical distribution system, but they can't change frequency of a supply circuit.
However, in most instances, 60Hz equipment can be operated from a 50Hz supply.
The input winding is in electrical series connection with the output winding; the input and output are not electrically isolated.
The standard Autotransformers are designed to change mains primary 230V into secondary 115V.
Technical data: Primary voltage : 230 volts, single phase, 50/60Hz.
Secondary voltage : 115 volts, 50¸2500VA.
Insulation class : B (130°C).
Dielectric Strength : 2000V primary & secondary - core.
