Open single-phase transformers for the power supply of appliances and assemblies. For applications with restricted spacing, HAHN´s unsealed transformers are a real alternative. New versions have been introduced by reducting the casing volume. Reduced weigts lead to reduced costs and can be realized in the form of printed circuit transformers, size EI 30 - EI 96 as well as UI 30 - UI 48. Applications for switch cabinets can be fitted with the sizes EI 60 - EI 150. Attachment facilities with angle pieces for top-hat rails are available. Impregnation with resin protects the unit against environmental impingmnets. The use of dual chamber bobbin windings guarantees an electrically safe galvanic separation to VDE 0570/EN 61 558 regulations. The materials employed meet insulation class B (130°C) minimum. Class F (155°C) is also available on request. |
