Description

The MI-Series is designed for applications utilizing distributed power architecture and is based on Vicor’s VI-200 / VI-J00 family of zero- current switching, component level DC-DC converters. Operating at frequencies up to 1 MHz, the MI-Series offers state-of-the-art performance in terms of power density, efficiency, noise, ease of use, and reliability.

All units are manufactured in ISO 9001-registered facilities. Vicor’s industry standard package enables the MI-Series to meet MIL-STD-810 environmental requirements for humidity, fungus, salt, fog, explosive atmosphere, acceleration, vibration, and shock.

Standard features such as wide output trimming / programming, current limiting, remote sense, logic enable / disable, and latching OVP and OTP combine to offer a high degree of protection, versatility, and reliability for military power systems.

Input Voltages:
  • 28 and 270 Vdc inputs perMIL-STD-704D/E/F
  • 155 Vdc input per MIL-STD-1399A
  • 165 Vdc input
Output Voltages:
  • 2 – 48 Vdc
Output Power:
  • 10 – 100 W
Efficiency:
  • Up to 90%
Dimensions:
  • MI-200 (full brick):4.6″x2.4″x0.5″ (116,9×61,0x12,7mm)
  • MI-J00 (half brick):2.28″x2.4″x0.5″ (57,9×61,0x12,7mm)

  • MIL-STD-810 and MIL-STD-202 qualified
  • NAVMAT component derating guidelines
  • 75 and 100 W booster modules available (MI-200 only)

  • MI-IAM – Input Attenuator Module— DC Input, front-end modules providing transient protection, inrush current limiting and EMI filtering for MI-200 and MI-J00 DC-DC converters.

  • MI-RAM – Ripple Attenuator Module — MI-RAM may be connected to MI-200 or MI-J00 converters with output voltages from 5 – 50 Volts, to limit total output noise to less than 3 mV peak-to-peak at loads up to 20 Amps.
  • MicroRAM – Ripple Attenuator Module— The MicroRAM combines both active and passive filtering to achieve greater than 40 dB of noise attenuation from over a range of 3 – 30 Vdc.

  • MI-AIM – AC Input Front-End Module — The MI-AIM is an AC front-end module which interfaces directly with AC mains to provide line rectification, EMI fltering, transient protection, and inrush lmiting.
