Description
The RSOE is a low cost isolated, regulated and short-circuit protected DC/DC converter designed for
industrial applications. A compact SIP8 case size, 2:1 input, 2kVDC isolation and a wide operating
temperature range of -40°C to +80°C without derating makes the RSOE series ideal for industrial,
transport and general-purpose on-board 5V power supplies. Industrial Class A EMC levels can be met
with a simple Pi-filter and the converters come with a three year warranty.
