Description
Single-phase safety isolating transformers are designed for supplying equipment in rooms for medical purposes. They are manufactured according to EN 61 558-2-15 with voltage transfer 230 V / 230 V, frequency 50 / 60 Hz, protection IP00, terminals IP20, insulation class F (155 °C), maximum ambient temperature 40 °C. Other voltage transfers are also possible, for example 400 V / 230 V. Transformers have reinforced insulation and shielding between primary and secondary windings, no-load current I0 < 3%, short-circuit voltage uk < 3%, voltage drop (regulation) ∆U < 5%, inrush current max. 8 times rated current (peak/peak). The transformers are equipped with a Pt100 temperature sensor. It can also be manufactured with the UP62 thermal expansion sensor (250 V / 2.5 A) upon agreement with the sales department.
Our range of single-phase safety isolating transformers for power supply in medical rooms is tested and certified according to EN 61558-2-15. Testing and certification was carried out by the Electrotechnical Testing Institute in Prague.
The certificate can be found here.
