Description
The RFS 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 and datacom input
voltages to isolated low output voltages. Proprietary patented manufacturing processes with full process
automation ensure optimal product quality. These are very high performance, cost effective converters with
a very small PCB footprint.
