9ASingle-phase transformers - composite UI core - vertical mounting JVT
JVR
JVD

Single-phase transformers with standard UI shape lamination with composite core are produced in accordance with ČSN EN 61 558 in any voltage transfer combination between 1 – 1 000 V, frequency 50/60 Hz, covering IP00, terminals IP20, isolation class B and maximum ambient temperature 40 °C. Their sizes and rated outputs are shown in the table. Transformer could be housed into IP23 steel case.

Different options are possible according to customer’s demand. For example: screening, higher temperature class, or ambient temperature, fuse on primary or secondary side etc. The power network voltage may vary ±10%, this should be considered to transformer power rating designation.

Provedení:

  • JVT – vertically mounted with transformer terminal blocks
  • JVR – vertically mounted with feed-through terminal blocks
  • JVD – vertically mounted with stud terminals on insulating plate
