VI RAM Ripple Attenuator Module is a filter output attenuator module that reduces output ripple to <3mV pk-pk. It is compatible with any VI-200/VI-J00 based product: 5 to 50VDC output. Full attenuation up to 20 amps is supported with no adjustments required. Converter sense, trim, overvoltage and overcurrent are also retained.
The VI RAM Ripple Attenuator Module is designed to lower output ripple on VI‑200/VI‑J00 based power supplies to less than 3 mV peak‑to‑peak. It works with a wide input range of 5 V to 50 V DC and can deliver up to 20 A of continuous current without requiring any user adjustments.
Key specifications include input and output voltage ranges of 5‑50 VDC, ripple performance of 3 mV pk‑pk (VI‑2) and 10 mV pk‑pk (VI‑J), efficiency between 93 % and 99 %, and a compact PCB mounting size of 58 × 61 × 13 mm. The module meets multiple temperature grades and standard approvals for reliable operation.
