The Hahn - “converter-platform”
Switch-mode power supply transformer up to 50 W
HAHN offers solutions for product developers of switching power supplies.
In response to the variety of designs which are available on the market, HAHN combines demands and wishes of the developers to quick solutions. Our “converter-platform” supplies switching power supply transformers up to 50 W according to the current requirements of IEC / EN 61558-2-16:2009 for double / reinforced insulation. With constructive suggestions and readily available components for creepage distance requirements> 5.5 mm, our “converter-platform” provides solutions for your power supply developments, regardless of your chosen and used switching regulator topology. With your design proposals or our available simulation and calculation programs, our R&D department realizes and delivers quick solutions. The “converter-platform” additionally accelerates the preparation of documents for quotes, design and manufacturing. Our self-developed measuring devices offer in advance the possibility to pattern your converters perfectly. The use of the same components (covered by our insulation system UL 1446 for insulation class B and F) and same structures in the development and production provides rationalization that will pay off for you. This stands for a quick and economical solution. The implementation of component tests, such as the additional requirements for insulation materials such as the coil former, according to EN 60335-1, paragraph 30, provide significantly more time- and cost savings for the certification of your application.
With design proposals and readily available components for creepage distances >5.5 mm, our "transformer platform" offers solutions for your power supply developments, regardless of the switching regulator topology selected and used.
