Single-phase transformer Type ETK

Within the range of up to 630 kVA, we supply single-phase transformers with input voltages of up to 1000 V. Their construction and design match the requirements of EN 61588 or VDE 0570, and possibly with other standards as well, such as UL / CSA. OpenSupply offers a number of designs, suitable for most applications. In their construction, we use high-quality materials and vacuum impregnation, for example in the Type ETK single phase control transformer.

Control transformers for the supply of control circuits, for example in switching devices, machines, etc. Designed and built according to VDE 0113 / EN 60204.



Open design (IP 00, installation max. IP 23)
Separate windings
Double insulation

  • Makes a more strenuous demand on test voltages and distances and spaces, because these types of transformers are regularly exposed to excessive voltage
  • Input adaptation taps
  • Spatial requirements according to DIN 41 308
  • Safe connections with screw terminals according to VBG 4 with self-lifting clamps (extra plug-in connection on request)
  • High-quality, vacuum impregnation using black polyester resin
  • Wear-resistant, heat-, UV- and solvent-resistant nameplate
  • Available on request up to 200 VA with DIN rail adapter
  • Customized variations are also available upon request
