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.

This pin provides an Off function which puts the converter into a low power mode. When the pin is ‘high’ the
converter is OFF and when the pin is high ‘Z’ the converter is ON. There is no allowed low state for this pin. Voltage
