A common question we get asked is whether two AC/DC converters can be wired in series to provide a higher voltage output.
Mean Well power supplies have isolated outputs so they can be linked in series to achieve whatever voltage you require.
For example two of the above NDR-480-48 converters can be wired in series to provide 96V. It is recommended that the power supplies used have similar current ratings.
As seen below, it is also recommended a diode be put in parallel with each power supply to prevent reverse voltage if one starts before the other.
