High-power-density, an industrial temperature range of -40°C to +100°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“. 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:
Note1: Derate to 75% if V

is <5VDC (refer to „Line Derating“ graph on page 2)
Note2: 12V 4:1 input also requires an external 10µF capacitor (refer to „Protection Circuit“ on page 3)
Note3: Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second
without damage the converter

Notes:
Note10: 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 open the converter is ON. There is no allowed low state for this pin. (refer to „ON/OFF CTRL“ on page 2)
