Features • 2:1 and 4:1 Wide input voltage range • SIP8 Package style DC/DC Converter • UL94V-0 Package material Regulated • Continuous short circuit protected • Low noise Converters RSO-S(D)(Z) • 1kVDC, 2kVDC or 3kVDC Isolation Description 1 Watt High-power-density, an industrial temperature range of -40°C to +100°C and extra features like SIP8 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 Single & Dual „/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.
