Type ESI single phase transformer

Transformers use magnetically coupled coils to increase / reduce decrease alternating current and / or the galvanic separation of primary and secondary circuits, which is why they play such an important role in providing security when working safely electricity.

In the design and construction of single-phase transformers, we use high-quality materials, while vacuum impregnation is also applied, for instance in the Type ESI single phase transformer.

This transformer is suitable for supplying electrical circuits or for devices that must be supplied with extra-low voltage (SELV, max. 50 V) (like hand lamps, portable equipment, toys, etc.)



  • Open design (IP 00, installation max. IP 23)
  • Coils separated by double / reinforced insulation (secure separation)
  • Spatial requirements in accordance with DIN 41308
  • Touch-safe connections according to VBG 4, with self-lifting clamps (additional plug-in available on request)
