VI-RAM-C2

Ripple attenuator modules may be connected to VI-200 or VI-J00 converters, FlatPACs, ComPACs or Mega Modules, with output voltages from 5 – 50 V, to limit output noise to less than 3 mV peak-to-peak at loads up to 20 A. Combining active and passive filtering, the VI-RAM attenuates both low frequency input power source fundamental and harmonics, as well as high frequency switching components in the frequency range of DC to 20 MHz, while exhibiting efficiencies of 93-99%. No adjustments are required, and remote sense and output voltage trim features are retained.

A member of 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.
