VI-RAM-I1 Description

Short technical summary and product information.

The Vicor VI-RAM-I1 is a ripple attenuator module designed to reduce output noise of Vicor VI-200 and VI-J00 series converters to less than 3mV peak-to-peak. It operates over an input voltage range of 5V to 50V DC and delivers up to 10A full load current (I1 grade). Combining active and passive filtering, it attenuates both low frequency input power fundamental and high frequency switching components from DC to 20MHz while maintaining efficiency between 93% and 99%. The module requires no adjustments and retains converter sense, trim, overvoltage, and overcurrent protection features. Packaged in a compact 2.28" x 2.4" x 0.5" module, it provides 500V RMS isolation from input/output to baseplate and operates over a baseplate temperature range of -40°C to +100°C.
