3 Phase Isolating Transformer / Vertical mounting versionDTS 0.1 - 2.0kVA according to IEC/DIN EN61558-2-4

overviewTechnische DatenPDF data sheet

Typical applications

3 phase isolating transformer according to IEC/EN61558-2-4 for general applications, e.g. for providing electrical (galvanic) isolation according to VDE0700/EN60335 regulations or network supply transformer (e.g. TN network system).

Specifications

3 phase isolating transformer according to EN61558-2-4. protection class I ready. Due to innovative vacuum impregnation in polyester varnish, the noise level is extraordinary low. Screw terminals are contact proof according to VBG4.

Standard switching matrix: Yyn0 (max. typical star load of phase current: approx. 10%). Switching matrix: Please note the distinction between different voltages (e.g. phase voltage, line voltage). For further information, don´t hesitate to contact us!

 

Any user-defined mounting position is possible.

3 Phase Isolating Transformers Circuits and Circuit Designs

3 phase isolation transformers offer various possibilities to connect PRIMARY and SECUNDARY winding.

Each design allows specific transformer characteristics. See the following table for preferred circuit designs.

  • Neutral wire “N“ or “n”. Percentage of neutral wire current allways refers to nominal current of phase conductor.
  • Please mind:

    • Secundary star circuit allows load on neutral wire.
    • Parallel connection of transformers must comply to following criteria:
      • Nominal voltage and rated frequency
      • Circuit design
      • Short circuit voltages
      • Ratio of rated loads should not extend 3:1
