Description
The RFM DC/DC converter is typically used in cost sensitive general purpose power isolation and
voltage matching applications. Despite its low cost, it is a fully specified converter with
1kVDC isolation, industrial operating temperature range of -40°C to +85°C without derating and UL/
EN certifications.
