Worldwide use independent of the local power supply: Markus Wöhrle from Endress+Hauser Wetzer in Nesselwang has designed a special power supply unit: It enables the company's own devices to be operated at a voltage of 24 volts as well as at 100 volts - as is common in Japan - or at European 230 volts. According to Wöhrle, this simplifies the company's own production and relieves the burden on system customers, who previously had to stock different devices for different applications.
