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. Transformers could be placed inside the IP56 plastic 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.
