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.

DC Input Filters
- 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.
DC Output Filters
- 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.
AC Input Filters and Frontends
- 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.
