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.

Input Voltages:
  • 24 Vdc
  • 48 Vdc
  • 300 Vdc
Output Voltage:
  • 1 – 95 Vdc with Vicor DC-DC converters
Output Power:
  • up to 400 W
Efficiency:

Dimensions(half brick):
  • 2.28″ x 2.4″ x 0.5″ (57,9 x 61,0 x 12,7 mm)
EMI / RFI Specifications:
  • Bellcore TR-TSY-000513
  • British Telecom BTR 2511
  • FCC Level “A”
  • EN55022 Level “B”

  • High surge withstand
  • Input polarity protection with external fuse
  • Logic disable
  • Expansion output for arrays
