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 created an impressive line of highly sophisticated products with innovative spirit and technical excellence. From the beginning W-IE-NE-R worked closely with nuclear physics laboratories. As a result development and production of NIM crates and electronics started in the 1980's. CAMAC modules and crates came in addition, followed by FASTBUS, VME and VXI, VME64x, VIPA and today's high-speed switched fabric technologies. Furthermore, W-IE-NE-R 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 combined with lowest noise and are built with highest quality. 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 often are used as design reference. All our products meet the requirements of the leading research centers around the world. We produce in accordance with ISO-Quality standards and CE rules.
