The Vicor VI-RAM-C2 is a Ripple Attenuator Module (RAM) designed to work with VI-200 or VI-J00 converters, as well as FlatPACs, ComPACs, or MegaMods. This component-level solution is engineered to limit total output noise to less than 3mV peak-to-peak, even at loads up to 20A.
Combining active and passive filtering techniques, the RAM attenuates both low-frequency input power source harmonics and high-frequency switching components across the DC to 20MHz frequency range. It achieves this while maintaining high efficiencies between 93% and 99%. No user adjustments are necessary, and features like remote sense and output voltage trim are preserved.
The VI-RAM-C2 offers power system architects a flexible way to achieve clean power, avoiding the space, efficiency, and weight penalties associated with linear power sources or the stability and adjustment issues of external add-on filters for conventional switchers. It operates within a temperature range of -25°C to +100°C.
