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.
