R1SE/H2
Description
1 Watt
3
The R±SE/H2 series are ±W unregulated DC/DC converters that are lower cost than equivalent
converters. The benefits of high volume production and semi-automatic assembly allow for a lower
selling price without sacrificing our high quality standards. They are UL certified for safety, offer
reasonable efficiency and still meet the full industrial operating temperature range of -41° to +±11°C.
All converters are ±110 tested in production and carry our 3-year warranty.
