2 Watt power supply in SMD package Features -40C to +100C operating temperature DC/DC Converter 3kVDC/1 second or 1kVDC/1 second isolation Unregulated No minimum load required IEC/EN/UL62368-1 certified, CB Report Converters R2SX Description 2 Watt The R2SX is a low profile, open-frame 2W SMD isolated DC/DC converter with either 3kVDC/1 second isolation (/H version) or 1kVDC/1 second isolation options. There is no minimum load requirement and SMD the efficiency stays high over a wide 20% to 100% load range. The operating temperature is from -40C up to +75C at full load, and up to +100C with derating. The converters are fully certified to Single Output IEC/EN/UL62368-1 and are 10/10 RoHS-conform. A simple low cost LC filter is all that is needed for Class B EMC compliance. The R2SX comes with a 3-year warranty. Selection Guide Part nom. Input Output Output Efficiency max.
