Transformers

Why choose EREA for your standard or custom transformer? EREA have more than half a century's experience in the manufacture of transformers for low voltage applications (up to 1000 VAC) with capacities ranging from a few VA up to hundreds of kVA. We have steadily expanded and modified our range of standard products over the years, as well as developing and fabricating thousands of custom transformers.  You can find our standard products via the product selector on this website or via our speedy selection cards. Contact us at any time to discuss your custom requirements. The information we need to draw up a quotation is set out here. Our single-phase and three-phase transformers, both available in step-up and step-down versions, can be further categorized by type.      ° Isolating transformers      ° Safety isolating transformers      ° Safety transformers      ° Control transformers      ° Autotransformers You can find further information on the different types and their applications in this summary. Transformers with specific features Extra energy-efficient transformers (ECO transformers) Many of our transformers are available in energy-efficient BTE versions. Thanks to their reduced energy costs these ECO transformers are not only ecologically sound, they are also exceptionally economical. Low inrush current transformers Transformers are increasingly found in smaller electrical installations (for example, for charging electric vehicles or in photovoltaic installations). Such installations often lack the current to deliver the brief burst of high inrush current required by the transformer. EREA have developed a series of low inrush current transformers (the IRC series) to cope with this situation. Unlike standard transformers the primary safety device is not required to be overdimensioned, instead the supply to the primary side of the transformer can be protected at its nominal current with a standard type C circuit breaker.
