Isolating transformers are aimed at isolating, adapting the voltage, as well as modifying the grounding scheme and dealing with electrical disturbances..

These low-voltage transformers are widely used in various fields of activity such as medical, nuclear, navy, industry, etc. For this product equipped with an enclosure, Circé offers standard housings (IP23-IK 08, IP33-IK 08, IP55-IK 08) which are available for indoor or outdoor use or in hazardous environments. If you require a specific enclosure, please do not hesitate to specify it on your request for quotation. Circé designs and manufactures single-phase isolating transformers according to your requirements while preserving the environment. As with all our products, each transformer is individually tested and each batch is delivered with its control report


Our single-phase isolating transformers comply with the norms EN 60076-11 ou EN 61558-2-1 / EC marking / EMC compatible.
