uwr models 3w, single output dc/dc converters 3 floating outputs since these are isolated dc/dc converters, their outputs are "floating." users may ground either the common (pins 5 and 7) for normal usage or the positive side (+output, pins 6 and 8) to effectively reverse the output polarity. filtering and noise reduction all uwr 3 watt dc/dc converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. in critical applications, input/output ripple and noise may be further reduced by installing electrolytic capacitors across the input terminals and/or low-esr tantalum or electrolytic capacitors across the output terminals. the caps should be located as close to the power converters as possible. typical values are listed in the tables below. in many applications, using values greater than those listed will yield better results. to reduce input ripple "d5" models 47f, 15v "d12" models 10f, 35v "d48" models 4.7f, 100v to reduce output ripple 5v output 47f, 10v, low esr 12/15v outputs 22f, 20v, low esr in critical, space-sensitive applications, datel may be able to tailor the internal input/output filtering of these units to meet your specific require- ments. contact our applications engineering group for additional details. input voltage: "d5" models 12 volts "d12" models 20 volts "d48" models 80 volts input reverse-polarity protection current must be <2a. brief duration only. fusing recommended. output overvoltage protection none output current current limited. max. current and short-circuit duration are model dependent.
