HAHN flat-type transformers UI 21, Ul 30, Ul 39, UI 48

An extensive standard range with capacities from 1.0 - 60.0 VA. HAHN transformers are quality products meeting all demands placed an highly developed electro-technical equipment. Of course, item quality certified, vacuum-encapsulated and tested with 6000V prim./sec. (VDE 0570 and CEE 15 regulations require only 3750 V). Leckage distance and air paths at least 10 mm. Temperature class ta 70'C/B as per VDE 0570, EN 61558 and CEE 15 regulations/standards. An innovative insulation technique in the provides for even greater primary and secondary voltage stability casting, in all sizes of the UI 30 to UI 39 types.
