Product Highlights
Ripple attenuator modules connected VI-200 VI-J00 converters, FlatPACs, MegaPACs, MasterModules MegaModules, with output voltages from 50V, limit output noise less than peak-to-peak loads 20A. Combining active passive filtering, VI-RAM attenuates both frequency input power source fundamental harmonics, high frequency switching components frequency range MHz, while exhibiting efficiencies 93-99%. adjustments required, remote sense output voltage trim features retained. member Vicor's high-power density, high performance, component-level power building blocks, VI-RAM offers power systems architect single, flexible, component-level solution almost "clean power" problem. same time, VI-RAM eliminates space, efficiency, weight penalties associated with linear power sources, stability, efficiency, adjustment penalties associated with external "add filters conventional switchers.

Electrical Considerations
Transient Response Dynamic Range: Full rated noise attenuation will maintained VI-RAM output step load changes rated output current source converter, with VI-RAM exhibiting underdamped output excursion less than Some degradation noise attenuation during transient response period following step exhibited larger load changes. Adding output capacitance VI-RAM will improve rejection over larger dynamic range.
Sense Connection: Sense-in sense-out connections provided VI-RAM. Sense-in
connections must connected corresponding sense connections Vicor converter. Sense-out pins VI-RAM must connected between VI-RAM power-output pins, point load.
Output Load Characteristics: When used combination with Vicor DC-DC converters, with
sense leads connected, VI-RAM will stable non-inductive load.
Voltage Drop: Below full load, input output Voltage Drop controlled essentially constant voltage which appears between -OUT terminals. overload voltage drop will rise current increases. tens millivolts appears between +OUT terminals. Care should taken connect terminals (i.e. through scope probe returns, grounds, etc.), attenuation will adversely affected.
