Conducted Noise vs. Load

Typical Vicor Module (VI-230-CV)
48 V Input, 5 V Output
Three common-mode chokes are offered as standard accessories.
NOTE: Common-mode filters may be common to one or
more modules, but only one should be used with modules
interconnected via GATE IN’s or, GATE OUT to GATE IN. As
an example, Driver / Booster arrays or Drivers with GATE IN’s
tied together to provide a common disable function.
