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.

Notes:

Note1: Efficiency is tested at nominal input and full load at +25°C ambient

Note2: Max Cap Load is tested at nominal input and full resistive load

Notes:

Note3: without suffix, standard isolation voltage (1kVDC/1 second)

with suffix „/H“, high isolation voltage (3kVDC/1 second)

Note4: with suffix „-R“, standard packaging tape and reel

with suffix „-Tray“ for optional tray packaging
