Variable toroidal transformers
Our variable toroidal transformers enable infinitely variable adjustment of the voltage from zero to the maximum value. They are connected via terminals and are prepared for protection class I. The one-phase and three-phase variable toroidal transformers are also offered with mounted motor drive for motorised adjustment.
Variable column-type transformers
Our variable column-type transformers enable infinitely variable adjustment of the voltage from zero to the maximum value. They are connected via terminals and are prepared for protection class I. The one-phase and three-phase version of the variable column-type transformers are both offered with mounted motor drive and limit switches for motorised adjustment.
