Description
The NDS Series of converters are low profile, single output, DC-DC converters intended for SMT placement and
reflow soldering. The product provides onboard conversion of standard telecom, datacom, and industrial input
voltages to isolated low output voltages. Proprietary patented manufacturing process ensures optimal quality with
full process automation. These are high performance, cost effective converters with an extremely small PCB
footprint.
