IAM – Input Attenuator Module

Input Power Supply Filter for 24 Vdc, 48 Vdc or 300 Vdc Input up to 400 Watt

Description IAM – Input Attenuator Module

The IAM Input Attenuator Module 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 IAM, in combination with 24, 48 and 300 Vdc input modules, provides a highly-efficient, high-density power system with outputs from 1 to 95 Vdc and power up to 400 Watts (expandable to 800 Watts). 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.
