High-power-density, an industrial temperature range of -40°C to +85°C and extra features like
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 choosing option "/H2"
or "/H3" in which case it is also ideal for medical applications which additionally require EN-60601-
1 certification. The standard version offers 2:1 input voltage range, while the “Z” version features 4:1
input voltage range, which includes an input voltage range covering both 5V and 12V supplies.

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The RSO series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.

CTRL Examples:
Pin 8 (NC*)
This pin is used internally and must have no external connection.
Pin 5 (NC)
Not connected internally.
Pin 3 (CTRL)
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.
NC = No Connection
NC* = NC, but no external Connection allowed.
