Three-phase variable toroidal transformers (economy winding, IP 00)
Description
REOVAR variable toroidal transformers from the market leader for variable transformers regulate the output voltage in fine steps with constant current at the output. Our variable toroidal transformers are suitable for frequencies from 50 – 400 Hz – other frequencies on request.
The particular advantage of these series is that the sinusoidal shape is retained – so there are no EMC problems.
The special core winding of REO generates no stray fields and a low voltage drop.
