DescriptionRipple attenuator modules of VI-RAM may be connected to VI-200 or VI-J00 converters, FlatPACs, MegaPACs, MasterModules or MegaModules, with output voltages from 5 to 50V, to limit output noise to less than 3mV peak-to-peak at loads up to 20A.
Combining active and passive filtering, the VI-RAM attenuates both low frequency input power source fundamental and harmonics, and high frequency switching components in the frequency range of DC to 20 MHz, while exhibiting efficiencies of 93-99%. No adjustments of VI-RAM are required, and remote sense and output voltage trim features are retained.
A member of Vicor's high-power density, high performance, component-level power building blocks, the VI-RAM offers the power systems architect a single, flexible, component-level solution to almost any "clean power" problem. At the same time, the VI-RAM eliminates the space, efficiency, and weight penalties associated with linear power sources, and the stability, efficiency, and adjustment penalties associated with external "add on" filters for conventional switchers.
