Safety isolating single-phase transformers with standard UI shape lamination, composite core and vertical mounting are intended for the power supply of equipment in medical locations. They are produced in accordance with ČSN EN 61 558-2-15 ed.2 with 230 V / 230 V voltage transfer, frequency 50 / 60Hz, protection IP00, terminals IP20, isolation class B or F and maximum ambient temperature of 40 °C. Other voltage transfers are also possible at input voltages up to 1000 V and output voltages up to 250 V. Transformers have reinforced insulation and protective shielding between the primary and secondary winding, magnetizing current < 3%, short-circuit voltage < 3%, voltages loss < 5%, and inrush current max. 8 times rated current (peak / peak). Transformers are equipped with a self resettable thermal switch 250 V / 2.5 A (also 15 A on request). Transformer could be housed into IP23 steel case.
