Description
The RNS series of converters are industry standard, 2” x 1” size, low profile, single output, DC/DC
converters intended for SMT placement and reflow soldering. The product provides on-board conversion of
a wide range of standard telecom, datacom and industrial input voltages to isolated low output voltages
without the need for any additional cooling. Proprietary patented manufacturing process ensures optimal
quality through full process automation. The converters are cost effective high performance alternatives to
competing products on the market.
