Some like it hot and cold

Some like it hot and cold
Especially the new PowerlinePLUS-Converters. They provide 20 to 50 watts and have been designed for applications with a temperature range of -55°C and 100°C.­ Converters with theses specifications are focussed to railway applications, aerospace, traffic controls, wind energy and semi military environments. They are however also ideal for industrial applications, in which heat generation has to be reduced.
