Description

MegaMod and MegaMod Jr. families of single, dual and triple output DC-DC converters provide power system designers with cost effective, high performance, off-the-shelf solutions to applications that might otherwise require a custom supply. MegaMods provide a chassis mounted alternative to board-mounted power supplies. The chassis mount package is alwo available for other select Vicor products.

Incorporating standard VI-200 or VI-J00 series DC-DC converters in rugged, chassis mount packages, MegaMod and MegaMod Jr.’s can be ordered with single, dual or triple outputs, having a combined output power of up to 600 W. Totally isolated outputs eliminate efficiency penalties and output interaction problems.

Input Voltages:
  • 10 – 400 Vdc
Output Voltages:
  • 2 – 95 Vdc
Output Power:
  • (MegaMod) 50 – 600 W
  • (MegaMod Jr.) 25 – 300 W
Efficiency:
  • 80 – 90% (typical)
Dimensions:
  • See mechanical drawing on data sheet

  • Up to 27 W/in3
  • Low noise ZCS / ZVS power architecture
  • Booster versions available for expanded output power – full size only
  • Single, dual, or triple outputs
  • RoHS compliant (VE- versions)

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

  • RAM — Ripple Attenuator Module — RAM may be connected to VI-200 or VI-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.

  • AIM – AC Input Front-End Module — The AIM is an AC front-end module which interfaces directly with AC mains to provide line rectification, EMI fltering, transient protection, and inrush lmiting.
  • HAM – Harmonic Attenuator Module — The HAM works in conjunction with a specific set of Vicor converters to deliver optimal efficiency, power and protection.
