Product Overview
The International Front End (IFE) is an
enclosed chassis mount, AC Front End
which may be used with VIPAC Arrays,
MegaModules or any of Vicor's 300V
input DC-DC converters to create a
complete, low profile, high density,
AC-DC power supply.
The IFE operates from worldwide AC
mains and includes autoranging line
rectification, integral EMI filtering,
hold-up capacitors, harmonic current
attenuation and transient suppression. The
IFE incorporates Vicor's passive harmonic
current attenuation technology and FARM
modules to deliver 500 Watts while
meeting EN61000-3-2 limits. All internal
heat producing components are coupled to
the chassis for optimal thermal transfer.
Two rugged, coldplate packages are
available—one with threaded inserts and
the other with thru hole flanges—which
may be mounted directly to a cabinet wall
or an existing heat sink for high
temperature operation.
The International Front Ends (IFE)
provide an off-the-shelf solution for many
custom and standard power supply
requirements where space constraints and
time to market are critical.
