Dual Separated Output DC-DC converters apply dual galvanic isolation, in addition to photoelectric isolation that aids in EMI suppression, elimination of ground loops and provides immunity to the system from external interference.

NOTE: The external capacitors (C2, C3) connected to the converter’s output are normally a maximum value of 10µF. The external resistances (R2/R3) connected to the converter output should be chosen according the following rule: the power consumption of R2/R3 is equal to 2~5% of the converter’s rated output power.
