Ripple Attenuator Module - RAM

Output ripple attenuator for VI-200/VI-J00

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

The RAM offers power systems architects a single, flexible, component-level solution to almost any clean-power problem. It also 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.
