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 sophisticatedindustrial-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-606011 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.

Notes
Note 1:

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter

Note 2: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.
