A variable-ratio transformer is used when output voltages are to be matched while constantly retaining sinusoidal form.
REOVAR toroidal transformers from the market leader for variable transformers regulate the output voltage in fine steps at constant current at the output.
The REO column-type variable transformers complement the REOVAR series for currents up to 1000A with a fine-step adjustment of the output voltage at a constant current at the output.
REO columns variable transformers with double brush system together with REO transformers are the perfect solution – the double performance is possible.
