This document describes the features and characteristics of the RP20-S_DEW series 20 Watt single and dual output POWERLINE DC/DC converters, including wide input voltage range, fixed operating frequency, 1.6kVDC isolation, etc.
The RP20 series from RECOM provides 20 W DC/DC converters with selectable single or dual output configurations. The devices operate from 9‑36 VDC (24 V nominal) or 18‑75 VDC (48 V nominal) input ranges and are certified to EN 60950 for safety‑critical telecom and other applications.
Key features include high efficiency (up to 79 %), tight voltage regulation (+‑2 % single, +‑5 % auxiliary), and optional heat‑sink versions for improved thermal performance. Detailed electrical characteristics, mechanical dimensions, and environmental ratings are listed for each part number.
