The conducted emissions from various SynQor DC-DC converters in a given product series but with different output voltages would not vary significantly. All the converters in a product series use the same conversion and regulation stage on the input side of the converter, and the output voltage variations are achieved with different turns ratios in the isolation stage. Because of this architecture, the ripple and conducted emissions, both common-mode and differential-mode, can be assumed to be independent of the output voltage.
Mil-COTS and InQor
MCOTS and InQor results are applicable to all output voltages of the MCOTS-28, MCOTS-28V, and IQ24 input voltage ranges for the HP, HZ, QT and SM series only.
*Met with common-mode capacitors and a metal screen shield covering the filter, converter and resistive load
