Why can I use a MI-IAM (Input Attenuator Module i.e., MI-A22-MU) with a VI-200 DC-DC converter (i.e., VI-2W0-MW)?
The primary reason is related to input voltage range compatibility, i.e., the MI-A22-MU is designed for 18 50 V operation and the VI-2W0-MW is designed for 18 36 V operation, this is a critical difference especially for input transient protection. With respect to EMI / RFI, the obvious impact of the input range mismatch has prevented this filter from being offered with this converter and thus performance has not been characterized to the MI-IAMs published specifications and as such, cannot be guaranteed.
