R2SX Single-Output Unregulated DC/DC Converters RECOM Power R2SX 2W Single-Output Unregulated DC/DC Converters are low-power, open-frame SMD isolated DC/DC modules with either 3kVDC/1 minute isolation (/H version) or 1kVDC/1 minute isolation options. No minimum load requirement exists, and the efficiency remains consistent over a wide 20% to 100% load range. The operating temperature range is from -40°C to +75°C at full load and to +100°C with derating. RECOM Power R2SX DC/DC converters are fully certified to IEC/EN/UL62368-1, 10/10 RoHS compliant, and have a three-year warranty.
