IAM™
Input Attenuator Module

IAM.jpg

Description

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 – 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.

Diagram
iam-block-diagram.jpg

The IAM consists of EMI filter and input protection circuitry. A zener diode in the EMI section provides reverse polarity protection while allowing full load operation with the correct input fuse. A zener, inductor capacitor in the EMI filter protect against short term transients. Longer transients are dropped across Q1. During normal operation, the FET is kept in saturation mode by connecting the Gate Out pin of the converter to the IAM. During an input overvoltage condition, Q2 is saturated bringing te Gate-In pin low and shutting down the converters to prevent possible damage. The IAM restarts automatically when the input is reduced to normal limits.
