Description
The NDS series of converters are low profile, single output, DC/DC converters intended for SMT placement
and reflow soldering. The product provides on-board 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.
