About Us

For more than 50 years W-IE-NE-R has followed its tradition of developing new technologies in advanced electronics for the benefit of science and industry. In the half century between 1959, when the company was founded by Hans Wiener, and now, our staff members have created an impressive line of highly sophisticated products with innovative spirit and technical excellence.

From the beginning, W-IE-NE-R has worked closely with nuclear physics laboratories. As a result, development and production of NIM crates and electronics started in the 1980s.  CAMAC modules and crates came shortly thereafter, followed by FASTBUS, VME, VXI, VME64x, VXS and today’s high-speed switched fabric technologies. W-IE-NE-R then began to specialize in custom high quality multi-channel power supplies for medium and high-power applications.

W-IE-NE-R crates and power supplies are known to provide the highest possible power output and lowest noise with quality and longevity in mind in every stage of the production process. Featuring modular construction and incorporating a unique level of local and remote diagnostic and control tools, W-IE-NE-R products are state of the art and are often used as a design reference.  All of our products meet the requirements of the leading research centers around the world.  We produce in accordance with ISO-Quality standards and CE rules.

Our treasured partnership with CERN LHC has led to the development of new radiation-hard and magnetic-field tolerant power supplies, as well as subsequent special crates in VME/VME64x, PXIe and other standards. Since 2006, W-IE-NE-R has manufactured over 2,000 standard and customized VME64x crates and radiation-hard power supplies for the CERN LHC accelerator and experiments, many of which are still in service after more than 20 years of use.

After 1992, the company operated as “W-IE-NE-R, Plein & Baus GmbH” under the ownership of Manfred Plein and Jürgen Baus and became an internationally distinguished supplier for electronic instrumentation for Particle Physics and related science with a worldwide operating sales and service network.

The USA sales and support center “W-IE-NE-R, Plein & Baus, Corp.” was established in 1997 in Springfield, Ohio in order to service the North American market.

In 2008 the W-IE-NE-R companies became subsidiaries of Phoenix Mecano AG, a Swiss-based global player in the components, packaging and electronics market. Phoenix Mecano components and enclosures are found in German high-speed trains as well as in Airbus airplanes. They are used in the automotive industry, the home and hospital care sector and in all areas of the machine and electronics industry. The name change to W-IE-NE-R Power Electronics underlined the focus on power conversion technology.

Synergies with our sister company Hartmann Electronic, a specialist for bus backplanes, as well as with other companies of the Phoenix Mecano holding benefitted from the development and production of new technologies. Thus W-IE-NE-R became a leading supplier of ruggedized, conduction cooled VPX power supplies. Together with Hartmann Electronic and Orion Technologies W-IE-NE-R formed the Rugged Computing group within Phoenix Mecano.

Through an acquisition in November 2023 W-IE-NE-R Power Electronics became part of the Kontron AG.

In 2021 W-IE-NE-R Power Electronics achieved the ISO 9001:2015 certification for its product development and production.

W-IE-NE-R Power Electronics will continue to serve the scientific research community, industry and Mil/Aero customers with high quality and state-of-the-art electronic instrumentation, chassis and power supplies.
