Description
High power-density, an industrial temperature range of -40°C to +85°C and extra features like Remote-On-
Off-control are just some of the characteristics of this converter, ideal for highly sophisticated industrial-
designs. The RSO series is available with isolation of 2kV or 3kV by chosing option "/H2" or "/H3" in which
case it is also ideal for medical applications which additionally require EN-60601-1 certification.
