The RNS / RND Series of converters are industry standard, 2 × 1” size,
low profile, single- and double-output DC-DC converters intended for
SMT placement and reflow soldering.
The product provides onboard 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.
