MIL-STD-810 Datasheet, PDF (1/1 Pages) Vicor Corporation – Military COTS Ripple Attenuator Modules

Product Highlights
The MI-RAM is designed for
applications where extremely low
noise outputs are required. When
used with any Vicor MI-Series
DC-DC converter, the MI-RAM
reduces both line frequency related
ripple and switching noise to less
than 10 mV p-p, DC to 20 MHz.
The combination of the MI-RAM
with an MI converter provides the
output noise performance of a
linear supply at a power density
in excess of 15 W/in³.
All of the features of the MI-Series
converter remain available while
using the MI-RAM, including
output voltage trimming, OVP and
OTP (MI-200 only), current limiting,
remote sense, and output inhibit.
All units are manufactured in ISO
9001-registered facilities. Full
epoxy encapsulation in a low
profile package enables the MI-RAM
to meet MIL-STD-810 environmental
testing requirements.
