Online UPS for industrial application

We developed with the ADUSV96 a new AC/DC converter with an input voltage range from 90 VAC to 264 VAC (46-63Hz) and a permanent output power of 96 Watts. This converter is made for the supply of electronic devices in industrial printers.In case of a power fail the UPS works on uninterruptably on battery charger. The unit is constructed in an open frame design and  measurements of 250x90x50mm and is operated in a closed chassis up to 60° C convection-cooled.

Wide-range DC/DC converter for railway technology

We offer with our new development a wide-range DC/DC converter with special specification.The DC/DC converter is meant for an input voltage range from 350 to 900 volt and delivers an output voltage of 24 volt with a rating of 200 watts. By special circuit topology the Converter reaches an efficiency of 92%.
