2 Watt power supply in SMD package

3kVDC/1 second or 1kVDC/1 second isolation
No minimum load required
IEC/EN/UL62368-1 certified, CB Report
Description
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
the efficiency stays high over a wide 20% to 100% load range. The operating temperature is from
-40°C up to +75°C at full load, and up to +100°C with derating. The converters are fully certified to
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.
