Variable autotransformers.

We have a wide range of single-phase, double and three-phase variable autotransformers. Our variable autotransformers are available for manual or motorized regulation.

On demand we can perform the autotransformer for use in desktop or in box with voltmeter and / or analog or digital ampmeter.

Our technical team has the experience and knowledge to be able to design variable autotransformers with no power limit..

General characteristics:

• Our variable autotransformers are designed with a high number of turns per volt that allows to select very accurate voltage values.

• Epoxy resin improves the heat dissipation, avoiding a heat concentration in the brush contact point.

• Temperature increase over ambient below 60°C.

• 100% of our variable autotransformers are verified.
