5ASingle-phase transformers - encapsulated in plastic case with leads or terminal blocks VV
VS
SS
HA

Encapsulated double-chamber single-phase transformers with standard EI shape lamination 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.

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.

Design:

  • VV – encapsulated transformer with cables
  • VS – encapsulated transformer with input cable and output terminals
  • SS – encapsulated transformer with input and output terminals
  • HA – encapsulated transformer type VV, VS or SS for halogen lights in class III
