Description
1 Watt
SIP8
Single & Dual
Output
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 VIN 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
