Product Highlights
The Input Attenuator Module (VI-IAM) is a component-level, DC input front end filter designed to occupy minimum board space while providing maximum protection for today's sophisticated electrical systems. The VI-IAM, in combination with Vicor 24, 48 and 300Vdc input modules, provides a highly efficient, high density power system with outputs from 1 to 95Vdc and power expandable from 25 to 800W. Your system will benefit from the small size, efficiency and inherent reliability of Vicor's component-level converters, while meeting the toughest demands of Telecommunications and Industrial power applications. This combination provides compliance with the transient requirements of Bellcore, British Telecom and IEC standards, and meets the EMI/RFI specifications of Bellcore, British Telecom and FCC Part 15, Subpart B and EN55022.
Note: For alternative product grades, change the "C" in the part number to "E", "I" or "M"
