For all areas of application in accordance with DIN EN 61558/VDE 0570

Our variable toroidal transformers in accordance with VDE 0552 with rotary knob and scale and our variable column-type transformers are an ideal solution wherever infinitely variable voltage transformation is required (e.g. for laboratory and testing devices). Both versions are available as one-phase transformers and as three-phase transformers. The variable toroidal and column-type transformers are designed as autotransformers with autotransformer windings.

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.
